The Cambodian–Vietnamese War (Khmer : សង្គ្រាមកម្ពុជា-វៀតណាម), otherwise known in Vietnam as the Counter-offensive on the Southwestern border (Vietnamese : Chiến dịch Phản công Biên giới Tây-Nam), was an armed conflict between the Socialist Republic of Vietnam and Democratic Kampuchea. The war began with isolated clashes along the land and maritime boundaries of Vietnam and Kampuchea between 1975 and 1978, occasionally involving division-sized military formations. On 25 December 1978, Vietnam launched a full-scale invasion of Kampuchea and subsequently occupied the country and removed the Communist Party of Kampuchea government from power.
Khmer or Cambodian is the language of the Khmer people and the official language of Cambodia. With approximately 16 million speakers, it is the second most widely spoken Austroasiatic language. Khmer has been influenced considerably by Sanskrit and Pali, especially in the royal and religious registers, through Hinduism and Buddhism. The more colloquial registers have influenced, and have been influenced by, Thai, Lao, Vietnamese, and Cham, all of which, due to geographical proximity and long-term cultural contact, form a sprachbund in peninsular Southeast Asia. It is also the earliest recorded and earliest written language of the Mon–Khmer family, predating Mon and by a significant margin Vietnamese, due to Old Khmer being the language of the historical empires of Chenla, Angkor and, presumably, their earlier predecessor state, Funan.
Vietnamese is an Austroasiatic language that originated in Vietnam, where it is the national and official language. It is the native language of the Vietnamese (Kinh) people, as well as a first or second language for the many ethnic minorities of Vietnam. As a result of Vietnamese emigration and cultural influence, Vietnamese speakers are found throughout the world, notably in East and Southeast Asia, North America, Australia and Western Europe. Vietnamese has also been officially recognized as a minority language in the Czech Republic.
The state of Kampuchea, officially Democratic Kampuchea, existed between 1975 and 1979 in present-day Cambodia. The state was controlled by the Khmer Rouge (KR) and was founded when KR forces defeated the Khmer Republic of Lon Nol in 1975.
During the Vietnam War, Vietnamese and Cambodian communists had formed an alliance to fight U.S.-backed regimes in their respective countries. Despite their open display of cooperation with the Vietnamese, the Khmer Rouge leadership feared that the Vietnamese communists were scheming to form an Indochinese federation with Vietnam as the dominant force in the region. In order to pre-empt an attempt by the Vietnamese to dominate them, the Khmer Rouge leadership began purging Vietnamese-trained personnel within their own ranks as the Lon Nol regime capitulated in 1975. Then, in May 1975, the newly formed Democratic Kampuchea, dominated by the Khmer Rouge, began attacking Vietnam, beginning with an attack on the Vietnamese island of Phú Quốc.
The Vietnam War, also known as the Second Indochina War, and in Vietnam as the Resistance War Against America or simply the American War, was an undeclared war in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. North Vietnam was supported by the Soviet Union, China, and other communist allies; South Vietnam was supported by the United States, South Korea, the Philippines, Australia, Thailand and other anti-communist allies. The war is considered a Cold War-era proxy war from some US perspectives. It lasted some 19 years with direct U.S. involvement ending in 1973 following the Paris Peace Accords, and included the Laotian Civil War and the Cambodian Civil War, resulting in all three countries becoming communist states in 1975.
The Khmer Rouge was the name popularly given to the followers of the Communist Party of Kampuchea (CPK) and by extension to the regime through which the CPK ruled in Cambodia between 1975 and 1979. The name had originally been used in the 1950s by Norodom Sihanouk as a blanket term for the Cambodian left.
In history, religion and political science, a purge is a removal of people who are considered undesirable by those in power from a government, another organization, their team owners, or society as a whole. A group undertaking such an effort is labeled as purging itself. Purges can be either nonviolent or violent; with the former often resolved by the simple removal of those who have been purged from office, and the latter often resolved by the imprisonment, exile, or murder of those who have been purged.
In spite of the fighting, the leaders of reunified Vietnam and Kampuchea made several public diplomatic exchanges throughout 1976 to highlight the supposedly strong relations between them. However, behind the scenes, Kampuchean leaders continued to fear what they perceived as Vietnamese expansionism. Therefore, on 30 April 1977, they launched another major military attack on Vietnam. Shocked by the Kampuchean assault, Vietnam launched a retaliatory strike at the end of 1977 in an attempt to force the Kampuchean government to negotiate. In January 1978, the Vietnamese military withdrew because their political objectives had not been achieved; the Khmer Rouge remained unwilling to seriously negotiate.
Small-scale fighting continued between the two countries throughout 1978, as China tried to mediate peace talks between the two sides. However, neither country could reach an acceptable compromise at the negotiation table. By the end of 1978, Vietnamese leaders decided to remove the Khmer Rouge-dominated regime of Democratic Kampuchea, perceiving it as being pro-Chinese and too hostile towards Vietnam. On 25 December 1978, 150,000 Vietnamese troops invaded Democratic Kampuchea and overran the Kampuchean Revolutionary Army in just two weeks, thereby ending the excesses of Pol Pot's regime which had been responsible for the deaths of almost a quarter of all Cambodians between 1975 and December 1978. Vietnamese military intervention and the occupying forces' subsequent allowing in of international food aid to mitigate the massive famine is viewed as ending the Cambodian genocide.
China, officially the People's Republic of China (PRC), is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering approximately 9,600,000 square kilometers (3,700,000 sq mi), it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, and the special administrative regions of Hong Kong and Macau.
the Kampuchean Revolutionary Army was the Armed Forces of Democratic Kampuchea.
The Cambodian genocide was carried out by the Khmer Rouge regime under the leadership of Pol Pot, and it resulted in the deaths of between 1.671 and 1.871 million people from 1975 to 1979, or 21 to 24 percent of Cambodia’s 1975 population. The Khmer Rouge wanted to turn the country into a socialist agrarian republic, founded on the policies of ultra-Maoism. In 1976, the Khmer Rouge changed the name of the country to Democratic Kampuchea. In order to fulfill their goals, the Khmer Rouge emptied the cities and forced Cambodians to relocate to labor camps in the countryside, where mass executions, forced labor, physical abuse, malnutrition, and disease were prevalent. This resulted in the death of approximately 25 percent of Cambodia's total population. Approximately 20,000 people passed through the Tuol Sleng Centre, one of the 196 prisons operated by the Khmer Rouge, and only 7 adults survived. The prisoners were taken to the Killing Fields, where they were executed and buried in mass graves. The abduction and indoctrination of children was widespread, and many were persuaded or forced to commit atrocities. The genocide triggered a second outflow of refugees, many of whom escaped to neighboring Vietnam and, to a lesser extent, Thailand. The Vietnamese invasion of Cambodia ended the genocide by defeating the Khmer Rouge in 1979.
On 8 January 1979, the pro-Vietnamese People's Republic of Kampuchea (PRK) was established in Phnom Penh, marking the beginning of a ten-year Vietnamese occupation. During that period, the Khmer Rouge's Democratic Kampuchea continued to be recognised by the United Nations as the legitimate government of Kampuchea, as several armed resistance groups were formed to fight the Vietnamese occupation. Behind the scenes, Prime Minister Hun Sen of the PRK regime approached factions of the Coalition Government of Democratic Kampuchea (CGDK) to begin peace talks. Under heavy diplomatic and economic pressure from the international community, the Vietnamese government implemented a series of economic and foreign policy reforms, which led to their withdrawal from Kampuchea in September 1989.
The People's Republic of Kampuchea was founded in Cambodia by the Salvation Front, a group of Cambodian communists dissatisfied with the Khmer Rouge after the overthrow of Democratic Kampuchea, Pol Pot's government. Brought about by an invasion from the Socialist Republic of Vietnam, which routed the Khmer Rouge armies, it had Vietnam and the Soviet Union as its main allies.
Phnom Penh, formerly known as Krong Chaktomuk or Krong Chaktomuk Serimongkul, is the capital and most populous city in Cambodia. Phnom Penh has been the national capital since French colonization of Cambodia, and has grown to become the nation's economic, industrial, and cultural center.
The United Nations (UN) is an intergovernmental organization that was tasked to maintain international peace and security, develop friendly relations among nations, achieve international co-operation and be a centre for harmonizing the actions of nations. The headquarters of the UN is in Manhattan, New York City, and is subject to extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development and upholding international law. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world. In 24 October 1945, at the end of World War II, the organization was established with the aim of preventing future wars. At its founding, the UN had 51 member states; there are now 193. The UN is the successor of the ineffective League of Nations.
At the Third Jakarta Informal Meeting in 1990, under the Australian-sponsored Cambodian Peace Plan, representatives of the CGDK and the PRK agreed to a power-sharing arrangement by forming a unity government known as the Supreme National Council (SNC). The SNC's role was to represent Cambodian sovereignty on the international stage, while the United Nations Transitional Authority in Cambodia (UNTAC) was tasked with supervising the country's domestic policies until a Cambodian government was elected by the people through a peaceful, democratic process. Cambodia's pathway to peace proved to be difficult, as Khmer Rouge leaders decided not to participate in the general elections, but instead they chose to disrupt the electoral process by launching military attacks on UN peacekeepers and killing ethnic Vietnamese migrants. In May 1993, Sihanouk's FUNCINPEC movement defeated the Cambodian People's Party (CPP), formerly the Kampuchean People's Revolutionary Party (KPRP), to win the general elections. However, the CPP leadership refused to accept defeat, and they announced that the eastern provinces of Cambodia, where most of the CPP's votes were drawn from, would secede from Cambodia. To avoid such an outcome, Norodom Ranariddh, the leader of FUNCINPEC, agreed to form a coalition government with the CPP. Shortly afterwards, the constitutional monarchy was restored and the Khmer Rouge was outlawed by the newly formed Cambodian Government.
The United Nations Transitional Authority in Cambodia (UNTAC) was a United Nations peacekeeping operation in Cambodia in 1992–93 formed following the 1991 Paris Peace Accords. It was also the first occasion on which the UN had taken over the administration of an independent state, organised and run an election, had its own radio station and jail, and been responsible for promoting and safeguarding human rights at the national level.
FUNCINPEC, National United Front for an Independent, Neutral, Peaceful and Cooperative Cambodia in English, is a royalist political party in Cambodia. Founded in 1981 by Norodom Sihanouk, it started off as a resistance movement against the People's Republic of Kampuchea (PRK) government. In 1982, it formed a resistance pact, the Coalition Government of Democratic Kampuchea (CGDK), together with the Khmer People's National Liberation Front (KPNLF) and the Khmer Rouge. It was one of the signatory parties of the 1991 Paris Peace Accords, which paved the way for the formation of the United Nations Transitional Authority in Cambodia (UNTAC). In 1992, FUNCINPEC became a political party and participated in the 1993 general elections organised by UNTAC. It won the elections, and formed a coalition government with the Cambodian People's Party (CPP), with which it jointly headed. Norodom Ranariddh, Sihanouk's son who had succeeded him as the party president, became First Prime Minister while Hun Sen, who was from the CPP, became Second Prime Minister.
The Cambodian People's Party, founded as the Kampuchean People's Revolutionary Party, is the current ruling political party of Cambodia. It was the sole legal party in the country at the time of the People's Republic of Kampuchea (1979–1989) and during the first two years of the State of Cambodia. Its name was changed during the final years of the State of Cambodia, when the single-party system as well as the Marxist–Leninist ideology were abandoned. Having governed Cambodia since 1979, it is one of the longest-ruling parties in the world. The General Secretary of the party from 1979 to 1981 was Pen Sovan. The KPRP was originally a Marxist–Leninist party, although it took on a more reformist outlook in the mid-1980s under Heng Samrin's leadership. In the 1990s, the KPRP officially dropped its commitment to socialist ideology altogether when it renamed itself the Cambodian People's Party. It is also currently the oldest active party in Cambodia. Since 2018, the party commands all 125 seats in the National Assembly, and 58 of 62 seats in the Senate. Hun Sen, the Prime Minister of Cambodia, has served as the party's President since 2015.
Angkor, the seat of the Khmer Empire, was subjected to Vietnamese influence as early as the 13th century. Vietnamese influence spread gradually and indirectly, and it was not until the early 19th century that Vietnam exercised direct control.In 1813, Nak Ong Chan gained the Cambodian throne with the help of Vietnam, and under his rule Cambodia became a protectorate. Following his death in 1834, Vietnam colonised Cambodia; it was governed under a Vietnamese administration and termed a Vietnamese 'province'. Throughout the 1830s, Vietnam attempted to erase Khmer culture, which had derived the basis of Cambodian society, dress and religion from India rather than China. The trend of Vietnamese dominance continued during French colonization, under which Cambodia was forced to cede much of its southern cone (which would later be Saigon, the Mekong Delta and Tây Ninh) to the Vietnamese. The Khmer Rouge later justified their incursions into Vietnam as an attempt to regain the territories which Cambodia had lost during the previous centuries.
Angkor was the capital city of the Khmer Empire, which also recognized as Yasodharapura and flourished from approximately the 9th to 15th centuries. Angkor was a megacity, supporting at least 0.1% of the global population during 1010–1220. The city houses the magnificent Angkor Wat, one of Cambodia's popular tourist attractions.
The Khmer Empire, officially the Angkor Empire, the predecessor state to modern Cambodia, was a Hindu-Buddhist empire in Southeast Asia. The empire, which grew out of the former kingdoms of Funan and Chenla, at times ruled over and/or vassalised most of mainland Southeast Asia and parts of Southern China, stretching from the tip of the Indochinese Peninsula northward to modern Yunnan province, China, and from Vietnam westward to Myanmar.
Ang Chan was king of Cambodia from 1806 to his death in 1834. He reigned under the name of Udaraja III.
The communist movement in Cambodia and Vietnam began before World War II with the founding of the Indochinese Communist Party (ICP), almost exclusively dominated by the Vietnamese, originally meant to fight French colonial rule in Indochina.In 1941, Nguyen Ai Quoc (commonly known by his alias Ho Chi Minh) founded the Viet Nam Doc Lap Dong Minh Hoi, or the Viet Minh. When the Japanese were defeated at the end of World War II, he initiated the first Indochinese war of independence against the French. During this time, Vietnamese forces made extensive use of Cambodian territory to transport weapons, supplies, and troops. This relationship lasted throughout the Vietnam War, when Vietnamese communists used Cambodia as a transport route and staging area for attacks on South Vietnam. In 1951, Vietnam guided the establishment of a separate Cambodian communist party, the Kampuchean People's Revolutionary Party (KPRP), which allied with a nationalist separatist Cambodian movement, the Khmer Serei (Free Khmers), in order to pursue independence. In accordance with the 1954 Geneva Accords negotiating the end of the French domination, newly created communist North Vietnam pulled all of its Viet Minh soldiers and cadres out of Cambodia; however, since the KPRP was staffed primarily by ethnic Vietnamese or Cambodians under its tutelage, approximately 5,000 Communist cadres went with them.
The power vacuum the Vietnamese communists left in their wake in Cambodia was soon filled by the return of a young group of Cambodian communist revolutionaries, many of whom received their communist education in France.In 1960, the KPRP changed its name to the Kampuchean Communist Party (KCP), and the name was later adopted by the majority coalition that formed around Saloth Sar (Pol Pot), Ieng Sary and Khieu Samphan as the 'true' political institution memorialising the KCP. This clique became the genesis of the Khmer Rouge, and its doctrine was heavily influenced by the Maoist ideology.
After overthrowing pro-China Sihanouk, Cambodian leader Lon Nol, despite being anti-Communist and ostensibly in the "pro-American" camp, backed FULRO against all Vietnamese, both anti-communist South Vietnam and the Communist Viet Cong. Lon Nol planned a slaughter of all Vietnamese people in Cambodia and a restoration of South Vietnam to a revived Champa state. Many were slaughtered and dumped in the Mekong River at the hands of Lon Nol's anti-Communist forces.The Khmer Rouge later imitated Lon Nol's actions.
The Khmer Rouge government adopted the mysterious term Angkar, or "the organisation", and the identities of its leaders remained confidential until 1977.The official head of state was Khieu Samphan, but the two men in control of the Party were Pol Pot and Ieng Sary. The ultimate objective of the Khmer Rouge was to erase the structure of the Cambodian state, which they viewed as feudal, capitalist, and serving the agendas of both the landholding elite and imperialists. In its place, they hoped to create a classless society based entirely on worker-peasants. The radical ideologies and goals of the Khmer Rouge were alien concepts to the masses. In fact, the socialist revolution held very little popular appeal, which led Pol Pot and his cadres to use ultra-nationalist sentiment, repressive and murderous rule, and propaganda aimed at demonising the Vietnamese to maintain their tenuous control.
Even before the Vietnam War ended, the relationship between the Khmer Rouge—which was in the process of seizing power from a US-backed regime headed by Lon Nol—and North Vietnam was strained. Clashes between Vietnamese communists and Khmer Rouge forces began as early as 1974, and the following year Pol Pot signed a treaty codifying the 'friendship' between the Khmer Rouge and China.
The conclusion of the Cambodian Civil War and the Fall of Saigon in April 1975 immediately brought a new conflict between Vietnam and Kampuchea. Although the North Vietnamese and the Khmer Rouge had previously fought side by side, the leaders of the newly created Democratic Kampuchea continued to view Vietnam with great suspicion, because they believed the Vietnamese Communists had never given up their dream of creating an Indochinese federation with Vietnam as the leader.For that reason, the Kampuchean Government decided to remove all North Vietnamese military forces from Kampuchean territory shortly after their capture of Phnom Penh on 17 April 1975. In the first major clash between the two former allies, the Kampuchean Revolutionary Army invaded the Vietnamese island of Phú Quốc on 1 May 1975 (barely 24 hours after Saigon fell), claiming it was part of Kampuchea's territory.
Nine days later, on 10 May 1975, the Kampuchean military continued its incursion by capturing the Thổ Chu Islands, where it executed 500 Vietnamese civilians. The Vietnamese military immediately responded to Kampuchean actions by launching a counter-attack and removing Kampuchean forces from Phu Quoc and Tho Chu, and then invading the Kampuchean island of Koh Wai.In June 1975, while on a visit to Hanoi, Kampuchean leader Pol Pot proposed that Vietnam and his country should sign a treaty of friendship and begin discussions on border disputes. However, those discussions never materialised, and the Kampucheans claimed that Vietnam turned down both offers. In August 1975, Vietnam returned the island of Koh Wai to Kampuchea and formally recognised Kampuchean sovereignty over the island.
Following those incidents, both countries attempted to improve their diplomatic relations with a series of congratulatory messages and exchange visits. On 17 April 1976, Vietnamese leaders sent a message to congratulate Khieu Samphan, Nuon Chea and Pol Pot on their "elections" as President, President of the People's Representatives and Premier of Kampuchea, respectively.Furthermore, the Vietnamese even denounced the alleged "U.S. bombing" of Siem Reap in February 1976, thereby reinforcing the Kampucheans' fictitious claim over the incident. In response, in June 1976, the Kampuchean leadership sent a message to the Provisional Revolutionary Government of the Republic of South Vietnam, which had governed South Vietnam since the fall of Saigon, congratulating them on the seventh anniversary of their establishment.
In July 1976, following the establishment of the Socialist Republic of Vietnam as a reunified country, Phnom Penh Radio broadcast a commentary which proclaimed the "militant solidarity and friendship between peoples of Democratic Kampuchea and the Socialist Republic of Vietnam grow constantly greener and sturdier".However, during that same month, Premier Pol Pot publicly hinted at tensions between Vietnam and Kampuchea when he told a visiting Vietnamese media delegation that there were "obstacles and difficulties" in the relationship between the two countries. Nonetheless, on 21 September 1976, the first air service connecting Hanoi and Ho Chi Minh City with Phnom Penh was established. Then in December 1976, the Kampuchean Revolutionary Organisation sent greetings to the Vietnamese Communist Party during their Fourth Congress.
Towards the end of 1976, while Vietnam and Kampuchea publicly appeared to be improving their relationships, the private suspicions of both countries' leadership grew. From the Vietnamese perspective, they were the patron of genuine Marxist–Leninist revolutions in South East Asia, so it was vital for them to exercise control over the Kampucheans and the Laotians.Indeed, that was the reason North Vietnam supported the Khmer Rouge during their fight against the Lon Nol regime, in the hope that the Kampuchean communists would adopt a pro-Vietnamese line upon their victory in the same way as the Pathet Lao had done. However, their hopes were dashed as early as 1973, because North Vietnamese military formations operating in Khmer Rouge-occupied territories were occasionally subjected to armed attacks by their own allies. The Vietnamese position inside Kampuchea was further weakened after the end of the war, as there were no pro-Vietnamese elements left within the Kampuchean Communist Party.
Thus, when the pro-Chinese Pol Pot and his brother-in-law Ieng Sary resigned from their respective positions as Premier and Foreign Minister in September 1976, Vietnamese Prime Minister Phạm Văn Đồng and General Secretary of the Communist Party Lê Duẩn were optimistic that Vietnam could exercise greater influence on the Kampucheans. In a private meeting with the Soviet ambassador to Vietnam on 16 November 1976, Lê Duẩn dismissed both Ieng Sary and Pol Pot as "bad people" for their pro-Chinese policies.Le Duan then asserted that Nuon Chea, who had ascended to the position of Premier of Democratic Kampuchea as Pol Pot's replacement, was a person of pro-Vietnamese orientation, so Vietnam could exercise its influence through him. However, the events which developed over the next few months would prove Lê Duẩn had been mistaken in his assessment of Nuon Chea.
Meanwhile, in Phnom Penh, the Kampuchean leadership had developed a seething fear and hatred of the Vietnamese leadership as a result of Vietnam's historical dominance over their country. From the Kampuchean perspective, the Vietnamese strategy to dominate Indochina involved infiltrating the communist parties of Kampuchea and Laos with Vietnamese-trained cadres.For that reason, when the first group of North Vietnamese-trained Khmer Rouge personnel returned to the country, they were immediately purged from the KCP. During the months following the defeat of the Lon Nol regime, Pol Pot continued to purge the KCP and the Government of Democratic Kampuchea of those who he believed to be Soviet and Vietnamese agents. Then, in the context of the triumphalism that prevailed among the Khmer Rouge leadership – they claimed they had single-handedly defeated the "American imperialists" – Democratic Kampuchea began preparing for war against Vietnam.
As the Kampuchean Revolutionary Army made preparations for its war against Vietnam, state-controlled media in Vietnam sent congratulatory messages to the Government of the Democratic Kampuchea on the second anniversary of its establishment, on 17 April 1977. On 30 April 1977, the second anniversary of the fall of Saigon, the Kampuchean reply came in the form of a military attack against the Vietnamese provinces of An Giang and Châu Đốc, killing hundreds of Vietnamese civilians.The People's Army of Vietnam (PAVN) responded by moving its troops to areas attacked by Kampuchea and, on 7 June 1977, Vietnam proposed high-level talks to discuss outstanding issues. On 18 June 1977, the Kampuchean Government replied by demanding that Vietnam remove all of its military units from the disputed areas, and create a demilitarised zone between the opposing forces.
Both sides ignored each other's proposals, and the Kampuchean Revolutionary Army continued sending soldiers across the border to attack Vietnamese towns and villages. In September 1977, Kampuchean artillery struck several Vietnamese villages along the border, and six villages in Đồng Tháp Province were overrun by Kampuchean infantry. Shortly afterwards, six divisions of the Kampuchea Revolutionary Army advanced about 10 kilometers (6.2 mi) into Tay Ninh Province, where they killed more than 1,000 Vietnamese civilians. Angered by the scale of Kampuchean assaults, the PAVN assembled eight divisions, estimated at around 60,000 soldiers, to launch a retaliatory strike against Kampuchea. On 16 December 1977, the PAVN divisions, with support from elements of the Vietnam People's Air Force, crossed the border along several axes with the objective of forcing the Kampuchean Government to negotiate.
On the battlefield, the Kampucheans quickly lost ground as their combat units were pushed back by the Vietnamese. By the end of December 1977, Vietnam had won a clear military victory over Kampuchea, as Vietnamese formations marched through Svay Rieng Province and only stopped short of entering the provincial capital. Despite the ferocity of the Vietnamese retaliation, the Kampuchean Government remained defiant. 38 kilometers (24 mi) from Phnom Penh, but the Vietnamese Government decided to withdraw its forces from Kampuchea because they had failed to achieve Vietnam's political objective. During the withdrawal, the Vietnamese military also evacuated thousands of prisoners and civilian refugees, including future leader Hun Sen.On 31 December 1977, Khieu Sampham declared that the Kampuchean Government would "temporarily" sever diplomatic relations with Vietnam until the Vietnamese military withdrew from the "sacred territory of Democratic Kampuchea". On 6 January 1978, PAVN divisions were only
Instead of being sobered by the Vietnamese show of force, the Kampuchean Government boasted that the Vietnamese withdrawal was a major victory for Democratic Kampuchea, comparing it to the "defeat of U.S. imperialism" on 17 April 1975. The Kampucheans went on further to proclaim that "our 6 January victory over the annexationist, Vietnamese aggressor enemy has given all of us greater confidence in the forces of our people and nation, in our Kampuchean Communist Party and our Kampuchean Revolutionary Army, and in our Party's line of people's war".The Kampuchean leadership claimed that one Kampuchean soldier was equal to 30 Vietnamese soldiers, so if Kampuchea could raise two million soldiers from a population of eight million, it could wipe out Vietnam's population of 50 million and still have six million people left. In reality, Kampuchean leaders simply ignored the condition of the population in their own country and Vietnam; the Vietnamese, though poor, were in good physical condition, while Kampuchea's population was physically and mentally exhausted from years of hard labour, starvation and disease.
In addition to the disparity in population, there was also a great disparity between the fighting capabilities of the armed forces of the two countries. In 1977, Vietnam was estimated to have 615,000 soldiers and 900 tanks, supported by a 12,000-member air force with 300 combat aircraft, including one squadron of light bombers. In comparison, Kampuchea had an army of 70,000, only a few heavy tanks, 200 armoured vehicles, and limited air capability.Despite facing such heavy odds, Kampuchea showed no signs of hesitation as its military continued to assault Vietnam's border regions. In January 1978, Kampuchean forces still held portions of Vietnamese territory and began overrunning Vietnamese outposts in Hà Tiên Province. On 27 January 1978, Vietnam started calling on the Kampuchean military along the border regions to overthrow the Khmer Rouge regime.
Against the backdrop of military clashes, between 9 January and 20 February 1978, Vietnamese Deputy Foreign Minister Phan Hien made several trips to Beijing to hold discussions with representatives of the Kampuchean Government, which ultimately proved to be fruitless. On 18 January 1978, China attempted to mediate further negotiations between Kampuchea and Vietnam when Vice Premier Deng Yingchao travelled to Phnom Penh, where she was met with strong resistance by Kampuchean leaders.Meanwhile, Vietnamese government officials began conducting secret meetings with So Phim, the Khmer Rouge leader in Kampuchea's Eastern Military Zone, to plan a military uprising backed by Vietnam. During that same period, military setbacks experienced by the Kampuchean Revolutionary Army in the Eastern Military Zone prompted Pol Pot to label the region as a "nest of traitors".
In order to purge the Eastern Military Zone of those he perceived to have been contaminated by the Vietnamese, Pol Pot ordered military units from the Southwest Zone to move into eastern Kampuchea and eliminate the "hidden traitors". Unable to withstand an attack from the Kampuchea Government, So Phim committed suicide while his deputy Heng Samrin defected to Vietnam. 2 kilometers (1.2 mi) into Vietnamese territory and massacred over 3,000 Vietnamese civilians in the village of Ba Chúc in An Giang Province.On 12 April 1978, the Kampuchean Government declared they and Vietnam could negotiate again if the Vietnamese gave up their expansionist ambitions and recognised Kampuchea's sovereignty. However, there was also a pre-condition requiring Vietnam to meet several obligations through a seven-month trial ceasefire. The Vietnamese Government immediately rejected the demand. In response, two Kampuchean divisions penetrated up to
In June 1978, the Vietnamese Air Force started bombing Kampuchean positions along the border regions, flying about 30 bombing sorties per day and inflicting heavy casualties on the Kampucheans. By that stage in the conflict, most surviving leaders of the Eastern Military Zone had escaped into Vietnam, where they assembled at various secret camps with the purpose of forming a Vietnamese-backed "liberation army" to fight against the Khmer Rouge regime.Meanwhile, the Vietnamese Communist Party Politburo was meeting in Hanoi to discuss its strategy for Kampuchea. It concluded that the Khmer Rouge regime was a proxy of China, which had been trying to fill the power vacuum following the withdrawal of the United States. As such, China was identified as Vietnam's main enemy, and its client regime in Phnom Penh had to be removed by conventional military force, because the Vietnamese adaptation of the Maoist "people's war" doctrine had not been a success against the Khmer Rouge's security apparatus.
To reflect the attitude of the country's leaders, Vietnam's state-controlled media stepped up its propaganda war against the Khmer Rouge, with the official Nhân Dân newspaper regularly calling for international intervention to save the Kampuchean people from domestic terror initiated by the Khmer Rouge regime. Furthermore, instead of sending congratulatory messages as they had done in the previous years, the Vietnamese media changed their tone and began referring to the Kampuchean Government as the "Pol Pot-Ieng Sary clique" as the Kampuchean military continued their campaign in Vietnam.By the end of June, the Vietnamese military assembled a multi-division task force to launch another limited-objective campaign against the Kampucheans. Again, the Vietnamese pushed the Kampuchean forces back into the provincial cities of Suong and Prey Veng and then pulled out. However, as they had done before, the Kampuchean Army moved its artillery back towards the border and continued shelling Vietnamese villages as though nothing had happened.
During the second half of 1978, Vietnamese leaders devoted much of their energy towards the military campaign against the Khmer Rouge regime, by seeking political support from the Soviet Union. In a briefing with Vietnamese Foreign Ministry officials on 25 July 1978, the Soviet chargé d'affaires in Hanoi was told that the Kampuchean Government had deployed 14 of its 17 regular army divisions and 16 local regiments along the border with Vietnam.Then, in early September 1978, Lê Duẩn informed the Soviet ambassador that Vietnam aimed to "solve fully this question of Kampuchea by the beginning of 1979". While Vietnam was laying the political foundation for the military campaign against Kampuchea, Soviet ships were reported to be unloading military hardware and ammunition in Cam Ranh Bay. In October 1978, Vietnamese radio broadcast what they claimed were accounts of uprisings against the Khmer Rouge regime, urging members of the Kampuchean military either to overthrow the "Pol Pot-Ieng Sary clique" or defect to Vietnam.
In a major turning point in the course of Soviet-Vietnamese and Sino-Vietnamese diplomatic relations, and ultimately the Vietnamese invasion of Kampuchea, a Treaty of Friendship and Cooperation was signed between Vietnam and the Soviet Union on 3 November 1978, which guaranteed the former of vital Soviet military aid in the scenario that China intervened in the conflict.Later, in November 1978, a command and control headquarters was established for the planned invasion of Kampuchea, with Senior General Lê Đức Anh taking full control of PAVN units along the border areas. The Vietnamese government drafted 350,000 men into the military to replace earlier losses and augment its units along the border. While the new recruits were completing training, ten divisions were deployed to the border regions of Long An, Đồng Tháp and Tây Ninh provinces. Vietnam also shifted three divisions based in Laos south towards the Laos-Kampuchea border. On 13 December 1978, the Chinese Government warned Vietnam that its patience was limited, and that Vietnam would be punished if it behaved in an "unbridled fashion".
Nonetheless, the final piece of the Vietnamese strategy emerged when Vietnam announced the formation of the Kampuchean United Front for National Salvation (KUFNS) in the "liberation zones" of Kampuchea.Hanoi claimed that KUFNS was an independent Kampuchean communist movement, with members drawn from all walks of life. Heng Samrin, formerly a member of the Khmer Rouge and commander of the Kampuchean 4th Division, was the chairman of the KUFNS Central Committee. Previously, the KUFNS was known as the Provisional Revolutionary Government of Kampuchea (PRGK), which consisted of 300 former Khmer Rouge cadres who defected to Vietnam. The PRGK regularly sent representatives abroad in search of support, before Vietnam abandoned the 'people's war' concept in favour of a conventional military campaign.
Not to be outdone by the Vietnamese military build-up, the Government of Democratic Kampuchea was busy strengthening its armed forces with Chinese support. In previous years, China had only provided the Kampuchean Revolutionary Army with a limited amount of arms and ammunition, but as relations with Vietnam worsened in 1978, Beijing established additional supply routes through Kampuchea and increased the volume of military hardware which travelled down each route.On the eve of the Vietnamese invasion, Kampuchea had an estimated 73,000 soldiers in the Eastern Military Zone bordering Vietnam. At that time, all branches of the Kampuchean armed forces were significantly strengthened by large quantities of Chinese-made military equipment, which included fighter aircraft, patrol boats, heavy artillery, anti-aircraft guns, trucks and tanks. Additionally, there were between 10,000 and 20,000 Chinese advisers in both military and civilian capacities, providing their support to the Khmer Rouge regime.
On 21 December 1978, Kampuchea's new-found strength was tested when a Vietnamese offensive, consisting of two divisions, crossed the border and moved towards the town of Kratie, while other support divisions were deployed along local routes to cut off the logistical tail of Kampuchean units.Despite enjoying generous support from China, the Kampuchean military could not withstand the Vietnamese offensive and suffered heavy casualties. Finally, on 25 December 1978, Vietnam launched a full-scale invasion using 13 divisions, estimated at 150,000 soldiers well-supported by heavy artillery and air power. Initially, Kampuchea directly challenged Vietnam's military might through conventional fighting methods, but this tactic resulted in the loss of half of the Kampuchean Revolutionary Army within two weeks. Heavy defeats on the battlefield prompted much of the Kampuchean leadership to evacuate towards the western region of the country. On 7 January 1979, the Vietnamese Army entered Phnom Penh along with members of the KUFNS. On the following day, a pro-Vietnamese Kampuchean state, known as the People's Republic of Kampuchea (PRK), was established, with Heng Samrin as the Chief of State and Pen Sovan as General Secretary of the Kampuchean People's Revolutionary Party.
The Khmer Rouge leadership, with much of its political and military structures shattered by the Vietnamese invasion, was forced to take refuge in Thailand, where it was warmly welcomed by the Thai Government. Despite the overwhelming economic challenges brought by the Khmer Rouge and the accompanying refugees, the Thai Government sheltered and protected the Khmer Rouge at Khao Larn camp in Trat Province.Meanwhile, in Phnom Penh, the new Kampuchean regime tried to rebuild the country's economic and social life, which was largely destroyed by decades of political upheavals and constant warfare. However, efforts to rebuild the country were severely hampered by the lack of educated and qualified personnel, as most educated people had either fled the country or had been murdered by the Khmer Rouge regime during the previous four years. By the end of the year, the new regime's attempts at nation-building were further challenged by several anti-Vietnamese resistance groups operating along the western regions of the country.
Shortly after the fall of Phnom Penh to Vietnamese forces and their Kampuchean allies in January 1979, representatives of Democratic Kampuchea called for an emergency meeting of the United Nations Security Council, so Prince Norodom Sihanouk could present the deposed regime's case. Despite strong objections from the Soviet Union and Czechoslovakia, the UN Security Council gave Sihanouk this chance.Although Sihanouk distanced himself from the human rights abuses of the Khmer Rouge, he accused Vietnam of using aggression to violate Kampuchea's sovereignty. As such, he demanded all UN countries to suspend aid to Vietnam and not recognise the Vietnamese-installed regime. Subsequently, seven non-aligned members of the UN Security Council submitted a draft resolution calling for a ceasefire and the withdrawal of all foreign forces from Kampuchea, which was endorsed by the People's Republic of China, France, Norway, Portugal, the United States and the United Kingdom. However, the resolution was not approved due to strong opposition from the Soviet Union and Czechoslovakia. Ted Galen Carpenter, a foreign policy analyst from the Cato Institute, argues that Vietnam did not invade Cambodia out of any noble desire to stop the atrocities committed by Pol Pot's regime but rather to consolidate their domination of Indochina.
Between 16–19 February 1979 Vietnam and the new Kampuchean regime held a summit meeting which concluded with the two countries signing a Treaty of Peace, Friendship and Cooperation.Article 2 of the treaty stated that the security of Vietnam and Kampuchea were interrelated; thus they would help defend each other "against schemes and acts of sabotage by the imperialist and international reactionary forces", thereby legitimising the presence of Vietnamese troops on Kampuchean soil. Soon afterwards, the Soviet Union, the socialist countries of Eastern Europe, and India recognised the Vietnamese-installed People's Republic of Kampuchea. The Soviet Government praised the PRK's "remarkable victory" and expressed its full support for the regime's advance towards socialism. Furthermore, the Soviets harshly criticised the Khmer Rouge regime's record of terror, which they implied had been imposed by China.
At the 34th Session of the UN General Assembly, representatives of the People's Republic of Kampuchea and Democratic Kampuchea both claimed the right to represent their country. The former also notified the member nations of the UN Security Council that it was the sole legitimate representative of Kampuchea and its people.In response, the UN Credentials Committee decided to recognise Democratic Kampuchea by a vote of six to three, despite the Khmer Rouge's blood-stained record while in power. Accordingly, representatives of Democratic Kampuchea were allowed to be seated in the General Assembly, with strong support from China. By January 1980, 29 countries had established diplomatic relations with the People's Republic of Kampuchea, yet nearly 80 countries still recognised the legitimacy of the deposed Democratic Kampuchea. At the same time, the Western powers and the member countries of the Association of South East Asian Nations (ASEAN) also voiced strong condemnation of Vietnam's use of force to remove the Khmer Rouge regime.
Thailand, which shared an 800-kilometer (500-mile) border with Kampuchea and has historically feared Vietnam's expansionism, demanded that Vietnam immediately remove its troops from Kampuchea so its people could elect a government free from foreign intervention. Indonesia, Malaysia, the Philippines and Singapore showed their support for Thailand's position.Furthermore, ASEAN viewed Vietnam's invasion and subsequent occupation of Kampuchea, which received strong Soviet support, as an intolerable threat to the region's security and stability. That view was shared by China, which went as far as accusing Vietnam of forcing Kampuchea into an Indochinese federation to serve as an outpost of Soviet global hegemony. The United States, which never maintained any form of diplomatic ties with the Khmer Rouge's Democratic Kampuchea, showed strong support for the membership of their former enemy in the UN General Assembly, and echoed ASEAN's call for an immediate withdrawal of Vietnamese military forces from Kampuchea.
In addition, North Korea, whose leader Kim Il-sung had offered Norodom Sihanouk sanctuary after he was ousted by Lon Nol in 1970,also refused to recognize the People's Republic of Kampuchea.
On 17 February 1979, China invaded Vietnam, aiming to capturing the capitals of its border provinces in order to force a Vietnamese withdrawal from Cambodia.The invasion was bogged down by resistance from local militias and some regular army reinforcements; nevertheless, the Chinese army captured Cao Bằng and Lao Cai after three weeks and Lạng Sơn after a month. The following day, China announced that it would not move deeper into Vietnam, apparently after meeting unexpectedly harsh resistance by well-trained Vietnamese forces equipped with Soviet and captured American weapons. Furthermore, Vietnam's politburo had ordered a general mobilization and begun planning for full conscription. The Chinese subsequently withdrew their forces. Although China failed either to decisively win the 27-day conflict or to force a withdrawal of Vietnamese forces in Cambodia, the diversion of troops from Kampuchea facilitated a resurgence in Khmer Rouge insurgent operations, making it unavoidable for the young PRK regime in Kampuchea to implement conscription. China's stationing of a large force on the border and engaging in border skirmishes during subsequent conflicts also required Vietnam to station a large portion of its army along the Sino-Vietnamese border throughout the 1980s.
When the Khmer Rouge regime was removed from power in January 1979, the Kampuchean people hoped that peace and liberty would return to their country. This was reinforced by the Constitution of the People's Republic of Kampuchea, proclaimed in 1981, which specifically stated that Kampuchea was an independent, peaceful state where power belonged to the people.However, there was a deep contrast between what was written within the Kampuchean constitution and reality, because the Kampuchean people began to despair at what they viewed as the Vietnamese occupation of their country, rather than a liberation that had freed them from the brutality of Democratic Kampuchea. That perception was reinforced by the presence of Vietnamese advisers who worked at every level of Heng Samrin's Kampuchean Government. In 1986, for example, there was one Vietnamese adviser for every Kampuchean cabinet minister and one adviser for each one of their three deputy ministers. Furthermore, it was reported that final decisions made by a Kampuchean minister had to receive final approval from the Vietnamese adviser, who usually dictated policies. Opposition to the Vietnamese was further fomented by human rights abuses committed by the Vietnamese and their allies. To fulfill its K5 Plan, a construction project to strengthen the Cambodia-Thai border, the PRK government conscripted 380,000 people, with large numbers succumbing to malaria. Claude Malhuret of Médecins Sans Frontières reported that a tactic the Vietnamese and KPRAF used to fight the Khmer Rouge was to withhold food from areas controlled by the Khmer Rouge. Thousands of tons of food provided by international relief organizations spoiled on the docks of Kompong Som. Food sent by aid organisations was often instead used to feed Vietnamese troops and Cambodians living under Vietnamese control.
To resist the Vietnamese occupation of Kampuchea and the regime which they installed, the Khmer Rouge called on the Kampuchean people to unite and fight the Vietnamese. However, due to the brutality which they had experienced under the deposed regime, many Kampucheans believed that any political movement aimed at restoring national freedom must oppose both the Khmer Rouge and the Vietnamese.In response to such preconditions, two non-communist movements were formed to fight the Vietnamese occupation. The first group, a right-wing and pro-Western organisation, was formed in October 1979 by former Prime Minister Son Sann and was called the Khmer People's National Liberation Front (KPNLF). The KPNLF operated from several refugee camps on the Thai-Cambodian border, where it controlled thousands of civilians. At its peak, the armed branch of the KPNLF were estimated to have between 12,000 and 15,000 fighters, but a third of that number were lost through fighting and desertions during the Vietnamese dry season offensive of 1984–85. Nonetheless, the KPNLF continued to operate in small groups, harassing the Vietnamese and their Kampuchean allies using guerrilla tactics.
The other non-communist organisation was the National United Front for an Independent, Peaceful, Neutral, and Cooperative Cambodia, formed by Sihanouk and known by its French acronym FUNCINPEC.The organization was formed after Sihanouk had severed ties with the Khmer Rouge following his representation on its behalf at the UN Security Council. As the leader of FUNCINPEC, Sihanouk called on the UN General Assembly to expel Khmer Rouge representatives for their crimes while in power and to keep Kampuchea's seat at the UN vacant on the basis that neither the Khmer Rouge nor the Vietnamese-installed PRK had the mandate to represent the Kampuchean people. He also criticised ASEAN for its continued recognition of the Khmer Rouge, and specifically Thailand for enabling Chinese arms shipments to travel through its territory to supply the notorious communist group. Despite the strength, effectiveness and popularity of the KPNLF and the FUNCINPEC, both resistance groups were plagued by internal divisions caused by the lack of unity, leadership struggles, corruption and alleged abuses of human rights.
In the early days of the Vietnamese occupation, the Kampuchean resistance groups had limited contact with each other due to their differences. Even though the Khmer Rouge enjoyed widespread international recognition, by 1980 the organization was under pressure from the international community to reform itself. ASEAN, which had backed the Khmer Rouge throughout their diplomatic confrontations with the PRK regime at the UN General Assembly in 1979, urged the Khmer Rouge leadership to put its blood-stained image behind it in order to join forces with other non-communist movements.The idea of forming an alliance with the Khmer Rouge initially caused a certain degree of uneasiness within the leadership circles of the FUNCINPEC and the KPNLF, because both groups were leery about joining with a communist organization well known for its brutality. Nonetheless, early in 1981, Sihanouk and Son Sann began engaging in talks with Khieu Samphan, President of the deposed Democratic Kampuchea, to discuss the prospect of forming an alliance.
In August 1981, unity talks between the three organizations appeared to have collapsed as a result of conflicting interests. Sihanouk, who feared the resurgence of the Khmer Rouge, proposed that all resistance groups disarm themselves following the withdrawal of Vietnamese troops from Kampuchea. Meanwhile, Son Sann demanded that the KPNLF be the lead organization within the proposed alliance, and the leaders of the Khmer Rouge "most compromised" by the atrocities in Kampuchea be exiled to China.Against these preconditions, Khieu Samphan reminded his rivals that the autonomy of the Khmer Rouge and Democratic Kampuchea should not be undermined. On 22 November 1982, Singapore, with the backing of ASEAN, proposed that three organizations form a coalition government with equal decision-making powers within the alliance. Singapore's proposal was welcomed by Sihanouk, who believed it was a fair deal for the non-communist movements.
Khieu Samphan, on the other hand, rejected that idea, viewing it as an attempt by Sihanouk and Son Sann to isolate the Khmer Rouge. However, Sihanouk knew that Chinese support would not be made available to the FUNCINPEC unless he made some compromises and joined the Khmer Rouge on their terms.So, in February 1982, Sihanouk met with Khieu Samphan in Beijing to work out their differences. In what he described as "another concession", Khieu Samphan proposed forming a coalition government without integrating the other resistance groups into institutions associated with Democratic Kampuchea. However, he emphasized that all parties must defend the legal status of Democratic Kampuchea as the legitimate state representing Kampuchea on the world stage. In May 1982, with the urging of Sihanouk, Son Sann decided to form a coalition government with the Khmer Rouge.
On 22 June 1982, leaders of the three organizations formalised the formation of their coalition government by signing a Thai-sponsored agreement which established the Coalition Government of Democratic Kampuchea (CGDK). Accordingly, the CGDK's Inner Cabinet consisted of Sihanouk as the President of Democratic Kampuchea, Khieu Samphan as the Vice-President in charge of foreign affairs and Son Sann as Prime Minister. Below the Inner Cabinet were six separate committees responsible for national defence, economy and finance, social affairs and public health, military affairs and the media.During a meeting between Kim Il-sung and Sihanouk on 10 April 1986, in Pyongyang, Kim Il-Sung reassured Sihanouk that North Korea would continue to regard him as the legitimate head of state of Kampuchea. By 1987, Democratic Kampuchea still held its membership at the UN General Assembly, even though it lacked four criteria of statehood: people, territory, government and supreme authority within the borders of a country. In spite of those limitations, forces of the three armed factions within the CGDK continued to fight the Vietnamese to achieve their objective of "bring[ing] about the implementation of the International Conference on Cambodia and other relevant UN General Assembly resolutions".
When the Vietnamese leaders launched their invasion of Kampuchea to remove the Khmer Rouge regime in 1978, they did not expect a negative reaction from the international community. However, the events that followed the invasion showed that they had severely miscalculated international sympathies toward their cause. Instead of backing Vietnam, most United Nations member countries denounced the Vietnamese use of force against Kampuchea, and even moved to revive the battered Khmer Rouge organisation that had once governed the country with such brutality.Thus, Kampuchea became more than just a military problem for Vietnam, quickly evolving into an economic and diplomatic problem in the international arena. Throughout the decade in which Vietnam occupied neighbouring Kampuchea, the Vietnamese Government, and the PRK regime which it installed, were placed on the periphery of the international community.
The international community's political stance towards Kampuchea had a severe impact on the Vietnamese economy, which was already wrecked by decades of continuous conflicts. The United States, which already had sanctions in place against Vietnam, convinced other countries of the United Nations to deprive Vietnam and the People's Republic of Kampuchea of much-needed funds by denying them membership to major international organisations such as the World Bank, the Asian Development Bank and the International Monetary Fund.In 1979 Japan stepped up the pressure by suspending all economic aid to Vietnam, and warned Vietnamese leaders that economic aid would only resume when Vietnam amended its policies towards Kampuchea, the Sino-Soviet rivalry and the problem of the boat people. Sweden, which was considered the staunchest supporter of Vietnam in the West, also considered reducing its commitments to the communist country as virtually every other country cancelled its aid.
In addition to external pressure, domestic policies implemented by the Vietnamese Government since 1975 had proven to be largely ineffective in stimulating the country's economic growth. By building on the Soviet model of central economic planning, Vietnam placed most emphasis on the development of heavy industries, while production in agriculture and light manufacturing sectors stagnated. million regular soldiers under arms, 180,000 of whom were stationed in Cambodia in 1984. Consequently, the Vietnamese Government had to spend one-third of its budget on the military and the campaign in Kampuchea, despite receiving $1.2 billion in military aid annually from the Soviet Union, thus further hampering Vietnam's economic rebuilding efforts.Furthermore, attempts to nationalise the economy of southern Vietnam after reunification only resulted in chaos, as economic output was driven down by dislocation of the general population. In addition to those failed economic policies, Vietnam maintained the fifth-largest armed forces in the world, with 1.26
In response to international pressure, and to avoid engaging in a debilitating conflict with various local armed resistance groups, Vietnam began withdrawing its military forces from Kampuchea as early as 1982. But the withdrawal process lacked international verification, so foreign observers simply dismissed Vietnam's movement of troops as mere rotations.In 1984, in order to disengage from Kampuchea, Vietnam unveiled a five-phase strategy known as the K5 Plan. The plan was authored by General Le Duc Anh, who had led the Vietnamese campaign in Kampuchea. The first phase required the Vietnamese military to capture the bases of armed groups in western Kampuchea and along the border with Thailand. The following phases included sealing off the border with Thailand, destroying local resistance groups, providing security for the population, and building up the Kampuchean People's Revolutionary Armed Forces. Foreign observers believed that the Vietnamese Army completed the first phase of the K5 Plan during the dry season offensive of 1984–85, when the base camps of several anti-Vietnamese resistance groups were overrun. Afterwards, the majority of ten Vietnamese divisions were assigned to operations on the frontiers, with the remainder staying in major provinces to protect the local population and to train the Kampuchean armed forces.
By 1985, international isolation and economic hardships had forced Vietnam to rely more and more on the Soviet Union for help. During the Chinese invasion in February 1979, the Soviet Union provided $1.4 billion worth of military aid to Vietnam, a figure that peaked at $1.7 billion in the period between 1981 and 1985. Then, to help Vietnam implement its third Five Year Plan (1981–1985), the Soviet Union provided a sum of $5.4 billion to the Vietnamese Government for its expenditures; economic aid ultimately reached $1.8 billion annually. The Soviet Union also provided 90 percent of Vietnam's demand for raw materials and 70 percent of its grain imports. Even though the figures suggest the Soviet Union was a reliable ally, privately Soviet leaders were dissatisfied with Hanoi's handling of the stalemate in Kampuchea and resented the burden of their aid program to Vietnam as their own country was undergoing economic reforms. In 1986, the Soviet Government announced that it would reduce aid to friendly nations; for Vietnam, those reductions meant the loss of 20 percent of its economic aid and one-third of its military aid.
To reengage with the international community, and to deal with the economic challenges brought by the changes in the Soviet Union and Eastern Europe, Vietnamese leaders decided to embark on a series of reforms. At the 6th National Party Congress in December 1986, newly appointed General Secretary of the VCP Nguyen Van Linh introduced a major reform known as Đổi Mới, the Vietnamese term for "renovation", in order to fix Vietnam's economic problems.However, Vietnamese leaders concluded that Vietnam's dire economic situation came as a result of the international isolation which followed its invasion of Kampuchea in 1978, and that for Đổi Mới to be successful it needed radical changes in defence and foreign policy. Subsequently, in June 1987, the Vietnamese Politburo adopted a new defence strategy in Resolution No. 2, calling for the complete withdrawal of Vietnamese soldiers from international duties, a reduction in the size of the army through a discharge of 600,000 soldiers and the establishment of a set ratio for military expenditures.
Then, on 13 May 1988, the Vietnamese Politburo adopted Resolution No. 13 on foreign policy, which aimed to achieve diversification and multilateralisation of Vietnam's foreign relations. Its main objectives were to end the embargoes imposed by UN members, integrate Vietnam with the regional and international community, and ultimately attract foreign investment and development aid.As part of this change, Vietnam ceased to regard the United States as a long-term foe and China as an imminent and dangerous enemy. In addition, official Vietnamese propaganda stopped labelling ASEAN as a "NATO-type" organisation. To implement the new reforms, Vietnam, with support from the Soviet Union, started transferring several years' worth of military equipment to the KPRAF, which numbered more than 70,000 soldiers. The Vietnamese Ministry of Defense's International Relations Department then advised its Kampuchean counterparts to only use the available equipment to maintain their current level of operations, and not to engage in major operations which could exhaust those supplies.
In 1988, Vietnam was estimated to have about 100,000 troops in Kampuchea, but, sensing that a diplomatic settlement was within reach, the Vietnamese Government began withdrawing forces in earnest. Between April and July 1989, 24,000 Vietnamese soldiers returned home. Then, between 21 and 26 September 1989, after suffering 15,000 soldiers killed and another 30,000 wounded during the 10-year occupation,Vietnam's commitment to Kampuchea was officially over, when the remaining 26,000 Vietnamese soldiers were pulled out. However, armed resistance groups opposed to the Vietnamese-installed PRK regime claimed that Vietnamese troops were still operating on Kampuchean soil long after September 1989. For example, non-communist groups engaging in land-grab operations in western Kampuchea after the withdrawal reported clashes with elite Vietnamese Special Forces near Tamar Puok along Route 69. Then, in March 1991, Vietnamese units were reported to have re-entered Kampot Province to defeat a Khmer Rouge offensive. Despite such claims, on 23 October 1991, the Vietnamese Government signed the Paris Peace Agreement, which aimed to restore peace in Kampuchea.
On 14 January 1985, Hun Sen was appointed Prime Minister of the People's Republic of Kampuchea and began peace talks with the factions of the Coalition Government of Democratic Kampuchea. Between 2–4 December 1987, Hun Sen met with Sihanouk at Fère-en-Tardenois in France to discuss the future of Kampuchea. Further talks occurred between 20–21 January 1988, and Hun Sen offered Sihanouk a position within the Kampuchean Government on the condition that he returned to Kampuchea straight away.However, Sihanouk did not accept the offer, even as preparations were made in Phnom Penh to receive him. Despite that failure, Hun Sen's Kampuchean Government was able to persuade Cheng Heng and In Tam, both ministers in Lon Nol's regime, to return to Kampuchea. In the first major step towards restoring peace in Kampuchea, representatives of the CGDK and the PRK met for the first time at the First Jakarta Informal Meeting on 25 July 1988. In that meeting, Sihanouk proposed a three-stage plan, which called for a cease-fire, a UN peacekeeping force to supervise the withdrawal of Vietnamese troops and the integration of all Kampuchean armed factions into a single army.
Vietnamese Foreign Minister Nguyen Co Thach urged all parties involved to separate Kampuchean problems into internal and external aspects. Therefore, to begin the process of restoring peace, the Vietnamese delegation proposed a two-stage plan that began with internal discussions among the Kampuchean factions, followed by a roundtable discussion with all involved countries. The Vietnamese proposal won out at the meeting, but no agreements were reached.At the Second Jakarta Meeting, on 19 February 1989, Australian Foreign Minister Gareth Evans forwarded the Cambodian Peace Plan to bring about a ceasefire, a peacekeeping force and the establishment of a national unity government to maintain Kampuchea's sovereignty until elections were held. To facilitate a peace agreement on the eve of the Vietnamese withdrawal, between 29–30 April 1989, Hun Sen convened a meeting of the National Assembly to adopt a new constitution, and the country was renamed the State of Cambodia to reflect the state of ambiguity of the country's sovereignty. Furthermore, Buddhism was re-established as the state religion, and citizens were guaranteed the right to hold private property.
In the meantime, however, peace talks between the warring factions continued, with the First Paris Peace Conference on Cambodia held in Paris in 1989. On 26 February 1990, following the withdrawal of Vietnamese troops, the Third Jakarta Informal Meeting was held, at which the Supreme National Council was established to safeguard Cambodian sovereignty. Initially, the Supreme National Council was to have 12 members, with three seats allocated to each faction of the CGDK, and three to the pro-Vietnam Kampuchean People's Revolutionary Party.However, Hun Sen objected to the proposed arrangement, calling instead for each faction of the CGDK to be given two seats for a total of six, and the Kampuchean People's Revolutionary Party to have six seats. In 1991 the Supreme National Council began representing Cambodia at the UN General Assembly. Then, in a bold move, Hun Sen renamed the Kampuchean People's Revolutionary Party as the Cambodian People's Party in an effort to portray his party as a democratic institution and renounce its revolutionary struggle.
On 23 October 1991, the Cambodian factions of the Supreme National Council, along with Vietnam and 15 member nations of the International Peace Conference on Cambodia, signed the Paris Peace Agreement. For the Cambodian people, two decades of continuous warfare and 13 years of civil war seemed to be over, although an atmosphere of uneasiness amongst the leaders of the Cambodian factions remained.In order to include the Khmer Rouge in the agreement, the major powers agreed to avoid using the word "genocide" to describe the actions of the Government of Democratic Kampuchea in the period between 1975 and 1979. As a result, Hun Sen criticised the Paris Agreement as being far from perfect, as it failed to remind the Cambodian people of the atrocities committed by the Khmer Rouge regime. Nonetheless, the Paris Agreement established the United Nations Transitional Authority in Cambodia (UNTAC), in accordance with the UN Security Council's Resolution 745, and gave UNTAC a broad mandate to supervise main policies and administration works until a Cambodian government was democratically elected.
On 14 November 1991, Sihanouk returned to Cambodia to participate in the elections, followed by Son Senn, a Khmer Rouge official, who arrived a few days later to set up the organisation's electoral campaign office in Phnom Penh.On 27 November 1991, Khieu Samphan also returned to Cambodia on a flight from Bangkok; initially he had expected his arrival to be uneventful, but as soon as Khieu Samphan's flight landed at Pochentong Airport, he was met by an angry crowd which shouted insults and abuse at him. As Khieu Samphan was driven into the city, another crowd lined the route towards his office and threw objects at his car. As soon as he arrived at his office, Khieu Samphan entered and immediately telephoned the Chinese Government to save him. Shortly afterwards, an angry mob forced its way into the building, chased Khieu Samphan up the second floor and tried to hang him from a ceiling fan. Eventually, Khieu Samphan was able to escape from the building by a ladder with his face bloodied, and was immediately taken to Pochentong Airport, where he flew out of Cambodia. With the departure of Khieu Samphan, the Khmer Rouge's participation in the election seemed doubtful.
In March 1992, the start of the UNTAC mission in Cambodia was marked by the arrival of 22,000 UN peacekeepers, which included troops from 22 countries, 6,000 officials, 3,500 police and 1,700 civilian employees and electoral volunteers.The mission was led by Yasushi Akashi. In June 1992, the Khmer Rouge formally established the National Union Party of Kampuchea, and announced that it would not register to participate in the upcoming elections. Furthermore, the Khmer Rouge also refused to disarm its forces in accordance with the Paris agreement. Then, to prevent ethnic Vietnamese from taking part in the elections, the Khmer Rouge started massacring Vietnamese civilian communities, causing hundreds of thousands of Vietnamese to flee Cambodia. Towards the end of 1992, Khmer Rouge forces advanced into Kampong Thom in order to gain a strategic foothold, before UN peacekeeping forces were fully deployed there. In the months leading up to the elections, several UN military patrols were attacked as they entered Khmer Rouge-held territory.
Despite ongoing threats from the Khmer Rouge during the elections, on 28 May 1993, FUNCINPEC won 45.47 percent of the vote, against 38.23 percent for the Cambodian People's Party.Though clearly defeated, Hun Sen refused to accept the results of the election, so his Defense Minister, Sin Song, announced the secession of the eastern provinces of Cambodia, which had supported the Cambodian People's Party. Prince Norodom Ranariddh, leader of FUNCINPEC and son of Sihanouk, agreed to form a coalition government with the Cambodian People's Party so the country would not break up. On 21 September 1993, the Cambodian Constituent Assembly approved a new Constitution and Ranariddh became First Prime Minister. He appointed Hun Sen as the Second Prime Minister. On 23 September 1993, the constitutional monarchy was restored with Norodom Sihanouk as the head of state. In July 1994, the Cambodian Government outlawed the Khmer Rouge for its continuous violations of the Paris Agreement. Most significantly, the Cambodian Government also specifically recognised the genocide and atrocities which occurred under Democratic Kampuchea. By 1998, the Khmer Rouge was completely dissolved.
The military occupation of Kampuchea had profound consequences for Vietnamese foreign policy. Since gaining independence in 1954, the Vietnamese communist perspective on foreign policy had been dominated by the need to maintain a world order of two camps, communist and non-communist.Indeed, the treaties of friendship that Vietnam signed with the Soviet Union, Laos and the People's Republic of Kampuchea were consistent with that view. However, the ideological motivations of the Vietnamese communist leadership were proven to be limited and heavily flawed, as demonstrated by the 1979 condemnation of Vietnam after ousting the Khmer Rouge regime. In the years that followed, the Vietnamese Government was left isolated from the world and its efforts to rebuild the country were handicapped by the lack of aid from the capitalist Western nations. Furthermore, the presence of Vietnamese military forces in Cambodia became an obstacle which prevented the normalisation of diplomatic ties with China, the United States and the member nations of ASEAN.
In light of the decline experienced by the Soviet Union and the socialist countries of Eastern Europe, the Vietnamese Government began repairing diplomatic relations with neighbouring countries as part of a greater effort to rejuvenate Vietnam's shattered economy. Since its invasion in 1979, China had placed sustained pressure on the northern borders of Vietnam, with the province of Ha Tuyen regularly shelled by Chinese artillery. In September 1985, Chinese bombardment of Ha Tuyen reached a peak when 2,000 rounds were fired.To reduce the state of hostility along the border region, and ultimately normalise relations with China, the Vietnamese Government dropped all hostile references to China at the 6th National Party Congress in December 1986, and also adopted the Doi Moi policy. In August 1990, as the Cambodian Peace Plan, authored by Australian Foreign Minister Gareth Evans, was being endorsed by the UN Security Council, both China and Vietnam moved towards accommodation.
Early in September 1990, Vietnamese Prime Minister Đỗ Mười, general secretary Nguyen Van Linh and former Prime Minister Pham Van Dong travelled to Chengdu, China, where they held a secret meeting with Chinese Prime Minister Li Peng and General Secretary of the Chinese Communist Party Jiang Zemin. On 17 September 1990, General Võ Nguyên Giáp also made a trip to China and thanked the Chinese Government for its past assistance.Despite outward signs of improvement in Vietnam's diplomatic relations with China, Vietnamese leaders were reluctant to endorse any peace plan which could weaken their client regime in Phnom Penh. However, as the four Cambodian factions reached an agreement on the power-sharing arrangement outlined at the Third Jakarta Informal Meeting in February 1990, Vietnam and China rapidly moved to re-establish formal diplomatic relations. In November 1991, newly elected Vietnamese Prime Minister Võ Văn Kiệt travelled to Beijing and met his Chinese counterpart, Li Peng, and they issued an 11-point communiqué re-establishing diplomatic ties between the two countries after 10 years without formal relations.
The end of the Cambodian conflict also brought an end to the ASEAN-imposed trade and aid embargo which had been in place since 1979. In January 1990, Thai Prime Minister Chatichai Choonhavan publicly voiced his support for Vietnam, and the rest of Indochina, to gain admission into ASEAN.In the period between late 1991 and early 1992, Vietnam restored relations with several member nations of ASEAN. As a result, between 1991 and 1994, investments from ASEAN countries made up 15 percent of direct foreign investment in Vietnam. Aside from the obvious economic benefits, ASEAN also provided a peaceful environment that guaranteed Vietnam's national security against foreign threats in the post-Cold War era, when Soviet aid was no longer available. Thus, on 28 July 1995, Vietnam officially became the seventh member of ASEAN, after leading ASEAN officials invited Vietnam to join at the ASEAN Ministerial Meeting in Bangkok in 1994. Then, in August 1995, the U.S. Liaison Office in Hanoi was upgraded to Embassy status, after U.S. President Bill Clinton announced a formal normalisation of diplomatic relations with Vietnam on 11 July 1995, thereby ending Vietnam's isolation from the United States.
Cambodia and Vietnam's forest cover underwent drastic changes following the end of the Khmer Rouge regime.The fall of Khmer Rouge was attributed to Vietnamese troops overthrowing the government and the takeover of Phnom Penh, establishing the People's Republic of Kampuchea (PRK) in 1978. With lack of international support by the end of the Cold War, Khmer Rouge struggled to rebuild itself. In an attempt to regain power and increase revenue, they established themselves along the Thailand-Cambodia border in Northwestern Cambodia to focus on exploiting Cambodia's natural resources including timber and rubies. With 15% of total global tropical forests, Southeast Asia is certainly a leader in timber production. This initiative quickly became an arms race between both political parties, when PRK imitated extraction efforts by Khmer Rouge.
From 1969 to 1995, Cambodia's forest cover depleted from 73% to 30–35%. million each year.Similarly, Vietnam lost nearly 3 million hectares of forest cover from 1976 to 1995. In 1992, Khmer Rouge became internationally isolated. The United Nations Security Council made the decision to ban all exports of Cambodian timber in November of that year. Efforts for a neutral electoral environment led to the establishment of the United Nations Transitional Authority (UNTAC) in Cambodia. The motion was implemented in January 1993. In the same year, the Vietnamese issued a logging ban, driving Khmer Rouge to practice illegal logging. A huge illegal trade took place from Cambodia to Vietnam worth USD$130
Thailand was the largest violator of UNTAC. million every month. Global Witness, an international human rights and environmental non-governmental organization (NGO) based in London, UK, recognized these timber guerillas when they identified mass Cambodian exports. They subsequently lobbied for an amendment in the United States Foreign Operations Act. The motion passed, thus the Act came to state that US assistance would no longer be given to any country deemed to be in military participation with the Khmer Rouge. Thailand closed borders with Cambodia the next day.The Thai government at the time insisted that Cambodian imported timber must have a certificate of origin approved by the governmental authorities in Phnom Penh. These certificates cost USD$35 for each cubic metre of timber for Khmer Rouge operating areas. Khmer Rouge therefore was forced to increase sale prices; they learned to speak Thai and therefore sold timber illegally to Thai timber operators, earning them over USD$10
Japan was the second largest offender of UNTAC, purchasing 8000 cubic metres of timber from Cambodia.There were 46 other identified offenders including the Korean Peninsula, Singapore, and Taiwan. After timber is produced by Cambodia or the greater Southeast Asia region, these "offender" countries re-process the logs which are subsequently transferred to North America, the Middle East, and Africa for sale.
PRK eventually offered Khmer Rouge re-integration into Cambodia's national armed forces as well as reconciliation between the two parties.In August 1996, the regional command of Khmer Rouge travelled back to Phnom Penh. Pol Pot, the former Prime Minister of the Democratic Kampuchea, and his lieutenants stayed in the Northern region to continue attempts at generating revenue from the extraction of natural resources. However, the group became severely weakened due to a lack of support. By 1998, Khmer Rouge had dissolved completely.
In 2010, the Royal Government of Cambodia set out a forest management plan called the National Forest Programme (NFP) in order to manage Cambodia's forest industry effectively in the long-term. million. The project has also been financed by the United Nations Development Programme through Target for Resource Assignment from the Core (UNDP-TRAC) with USD$500,000, the United Nations Development Programme through Sustainable Forest Management (UNDP-SFM) with USD$250,000, the United Nations Development Programme through Conservation Areas through Landscape Management (UNDP-CALM) with USD$150,000, and the Food and Agriculture Organization (FAO) with USD$300,000.A number of donors had been in support of the United Nations Programme on Reducing emissions from deforestation and forest degradation (UN-REDD). UN-REDD itself contributed over USD$3
REDD+ is a collaborative programme negotiated under the United Nations Framework Convention on Climate Change (UNFCCC), where NGOs, individuals, developed countries, and the private sector will fund developing countries in order to reduce forest emissions.Eligibility to be a contributor is determined by the potential donor's own sustainable forest management, carbon stock enhancement, and emission reduction. Estimation of carbon dioxide emissions can be done by calculating change in carbon stock. This can be done by monitoring forest land, and summing land area and the average forest stock. Despite these positive outcomes, including increased revenue for sustainable forest practices in the developing world, international strategic planning, and ensuring reliable performance and monitoring, forest governance literature makes a number of criticisms towards REDD+. Corbera & Schroeder raise the concern that Indigenous and forest-dependent individuals could lose rights to their forest resources upon implementation. Additionally, over the last few decades, forest management in the developing world had been heading towards a decentralised trajectory. The initiation of REDD+ may threaten the transition to allowing local actors more agency over their own forest management system.
UNDP-TRAC is a three track funding scheme initiated by James Gustave Speth, the former UNDP Administrator appointed in 1993.Prior to 1991, the UNDP had little affiliation with environmental sustainability. That year, the Global Environment Facility was made a UNDP partner after an agreement with the World Bank. This led to active participation by the UNDP in the United Nations Conference on Environment and Development during the following year. The decision made by former Secretary-General Boutros Ghali to appoint Speth facilitated strong strides in sustainable development within the UNDP. Speth was a renowned environmentalist in the United States, changing UNDP motto from "Human Development" to "Sustainable Human Development". Prior to these events, the UNDP's environmental emphasis was miniscule and had only one passing mention within the 1987 Brundtland report.
The Department of Forestry and Wildlife and the Cambodia Tree Seed Project was in collaborative support of developing the Royal Government of Cambodia's NFP.NFP's objective is to contribute optimally to poverty alleviation and macro-economic growth through sustainable forest management and conservation with active stakeholder participation, particularly in rural areas.
Pol Pot was a Cambodian revolutionary and politician who served as the general secretary of the Communist Party of Kampuchea from 1963 to 1981. Ideologically a Marxist–Leninist and Khmer nationalist, he led the Khmer Rouge group from 1963 until 1997. From 1976 to 1979, he served as the Prime Minister of Democratic Kampuchea.
Norodom Sihanouk was a Cambodian royal, politician, composer and filmmaker who was twice King and numerous times Prime Minister of Cambodia. In Cambodia, he is also known as Samdech Euv. Until the early years of his rule, his family ruled over the French Protectorate of Cambodia.
The Khmer Rouge period refers to the rule of Pol Pot, Nuon Chea, Ieng Sary, Son Sen, Khieu Samphan and the Communist Party of Kampuchea over Cambodia, which the Khmer Rouge renamed Democratic Kampuchea.
The Kingdom of Cambodia, informally known as the first Kingdom of Cambodia and the Sangkum Reastr Niyum era, referred to Norodom Sihanouk's first administration of Cambodia from 1953 to 1970, an especially significant time in the country's history. Sihanouk continues to be one of the most controversial figures in Southeast Asia's turbulent and often tragic postwar history.
The Cambodian Civil War was a military conflict that pitted the forces of the Communist Party of Kampuchea and their allies the Democratic Republic of Vietnam and the Viet Cong against the government forces of the Kingdom of Cambodia and, after October 1970, the Khmer Republic, which were supported by the United States (U.S.) and the Republic of Vietnam.
Son Sen, alias Comrade Khieu (សមមិត្តខៀវ), was a Cambodian Communist politician and soldier. A member of the Central Committee of the Communist Party of Kampuchea/Party of Democratic Kampuchea, the Khmer Rouge, from 1974 to 1992, Sen oversaw the Party's security apparatus, including the Santebal secret police and the notorious security prison S-21 at Tuol Sleng.
Khieu Samphan is a former Cambodian communist politician who was the chairman of the state presidium of Democratic Kampuchea (Cambodia) from 1976 until 1979. As such, he served as Cambodia's head of state and was one of the most powerful officials in the Khmer Rouge movement, although Pol Pot remained the General Secretary in the party. Khieu Samphan is the second oldest living former Khmer Rouge leader, alongside Nuon Chea. On 7 August 2014, they were convicted and received life sentences for crimes against humanity during the Cambodian Genocide, and a further trial found him guilty of genocide in 2018.
Nuon Chea, also known as Long Bunruot or Rungloet Laodi, is a Cambodian former politician who was the chief ideologist of the Khmer Rouge. He also served as the Prime Minister of Democratic Kampuchea.
The Coalition Government of Democratic Kampuchea, renamed to the National Government of Cambodia from 1990, was a coalition government in exile composed of three Cambodian political factions, namely Prince Norodom Sihanouk's FUNCINPEC party, the Party of Democratic Kampuchea and the Khmer People's National Liberation Front (KPNLF) formed in 1982, broadening the de facto deposed Democratic Kampuchea regime. For most of its existence, it was the internationally recognized government of Cambodia.
Hu Nim, alias "Phoas" (ភាស់), was a Cambodian Communist intellectual and politician who held a number of ministerial posts. His long political career included spells with the Sangkum regime of Prince Norodom Sihanouk, the Communist guerrilla resistance, the GRUNK coalition government-in-exile, and the administration of Democratic Kampuchea, when the country was controlled by the Communist Party of Kampuchea.
The Sangkum Reastr Niyum, literally the "community of the common people", was a political organisation set up in 1955 by Prince Norodom Sihanouk of Cambodia. Though it described itself as a 'movement' rather than a political party, the Sangkum retained control of the government of Cambodia throughout the first administration of Sihanouk, from 1955 to 1970.
The National Day of Remembrance, formerly called the National Day of Hatred, which falls on May 20, is an annual event in Cambodia. It commemorates the Cambodian genocide of the Khmer Rouge regime that ruled the country between 1975 and 1979. It became a national holiday in 2018.
The Khmer United National Front was an organisation formed by the deposed King of Cambodia, Norodom Sihanouk in 1970 while he was in exile in Beijing.
The GRUNK, a French acronym for Royal Government of the National Union of Kampuchea, was a government-in-exile of Cambodia, based in Beijing, that was in existence between 1970 and 1976. Officially, it was briefly in control of Cambodia between 1975 and 1976.
General Sak Sutsakhan was a Cambodian politician and soldier who had a long career in the country's politics. He was the last Head of State of the Khmer Republic, the regime overthrown by the Khmer Rouge in 1975. Sak Sutsakhan formed a pro-US force known as the "Khmer Sâ".
General elections were held in Cambodia on 1 May 1981 and marked the establishment of the new, Vietnamese-backed, state of the People's Republic of Kampuchea (PRK). The Kampuchean People's Revolutionary Party was the only party to contest the election, and won all 117 seats. Voter turnout was reported to be 90%.
The Communist Party of Kampuchea, also known as Khmer Communist Party (KCP), was a communist party in Cambodia. Its leader was Pol Pot and its followers were generally known as Khmer Rouge. The party was underground for most of its existence and took power in the country in 1975 and established the state known as Democratic Kampuchea. The party lost power in 1979 with the establishment of the People's Republic of Kampuchea by leftists who were dissatisfied by the Pol Pot regime and by the intervention of Vietnamese military forces after a period of mass killing. The party was officially dissolved in 1981, with the Party of Democratic Kampuchea claiming its legacy.
There are allegations that the United States (U.S.) supported the Khmer Rouge during the Cambodian–Vietnamese War in order to weaken the influence of Vietnam and the Soviet Union in Southeast Asia. Details of alleged U.S. actions that benefited the Khmer Rouge range from tolerating Chinese and Thai aid to the organization to directly arming the Khmer Rouge. The U.S. government officially denies these claims, and Nate Thayer defended U.S. policy, arguing that little, if any, American aid actually reached the Khmer Rouge. However, it is not disputed that the U.S. voted for the Khmer Rouge and the Coalition Government of Democratic Kampuchea (CGDK), which was dominated by the Khmer Rouge, to retain Cambodia's United Nations (UN) seat until 1982 and 1991, respectively. Furthermore, an investigation by the United States Department of State acknowledged that U.S. material support for the Khmer Rouge's CGDK partners indirectly benefited the Khmer Rouge.
