Vietnam is located on the eastern margin of the Indochinese peninsula and occupies about 331,211.6 square kilometres (127,881.5 sq mi), of which about 25% was under cultivation in 1987. It borders the Gulf of Tonkin, Gulf of Thailand, and Pacific Ocean, along with China, Laos, and Cambodia. The elongated roughly S shaped country has a north-to-south distance of 1,650 km (1,030 mi) and is about 50 km (31 mi) wide at the narrowest point. With a coastline of 3,260 km (2,030 mi), excluding islands, Vietnam claims 12 nautical miles as the limit of its territorial waters, an additional 12 nautical miles as a contiguous customs and security zone. It has an exclusive economic zone of 417,663 km2 (161,261 sq mi) with 200 nautical miles.
The People's Army of Vietnam (PAVN), officially the Vietnam People's Army, also recognized as the Vietnamese Army or the People's Army, is the national military force of the Socialist Republic of Vietnam and the armed wing of the ruling Communist Party of Vietnam (CPV). The PAVN is a part of the Vietnam People's Armed Forces and includes: Ground Force, Navy, Air Force, Border Guard and Coast Guard. Vietnam does not have a separate Ground Force or Army service. All ground troops, army corps, military districts and special forces belong to the Ministry of National Defence, directly under the command of the CPV Central Military Commission, the Minister of National Defence, and the General Staff of the Vietnam People's Army. The military flag of the PAVN is the National flag of the Socialist Republic of Vietnam defaced with the motto Quyết thắng added in yellow at the top left.
Tonkin, also spelled Tongkin, Tonquin or Tongking, is an exonym referring to the northern region of Vietnam. During the 17th and 18th centuries, this term referred to the domain Đàng Ngoài under Trịnh lords' control, including both the Northern and Thanh-Nghệ regions, north of the Gianh River. From 1884 to early 1945, this term was used for the French protectorate of Tonkin, composed of only the Northern region.
Cochinchina or Cochin-China is a historical exonym for part of Vietnam, depending on the contexts. Sometimes it referred to the whole of Vietnam, but it was commonly used to refer to the region south of the Gianh River.
On the first tier, Vietnam is divided into fifty-eight provinces (tỉnh) and five municipalities under the command of the central government. Municipalities are the highest-ranked cities in Vietnam. Municipalities are centrally-controlled cities and have special status equal to the provinces.
The Mekong Delta, also known as the Western Region or South-western region, is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of south-western Vietnam of over 40,500 km2 (15,600 sq mi). The size of the area covered by water depends on the season. Its wet coastal geography makes it an important source of agriculture and aquaculture for the country.
Cần Thơ, also written as Can Tho or Cantho, is the fourth-largest city in Vietnam, and the largest city along the Mekong Delta region in Vietnam.
The Khmer Krom are ethnically Khmer people living in or from the Mekong Delta, the south western part of Vietnam known in Khmer as Kampuchea Krom. The Khmer Krom people are considered as the Indigenous people of Southern Vietnam and having the oldest extant recorded history of inhabiting in the region. In Vietnam, they are recognized as one of Vietnam's fifty-three ethnic minorities.
Quảng Ninh or Quangninh is a province along the northeastern coast of Vietnam. It is about 153 km (95 mi) east of Hanoi, comprising four cities, two district-level towns and seven rural districts. The provincial capital is Hạ Long. The province covers an area of 6178.21 square kilometres and, as of 2019, had a population of 1,320,324. Nearly 80% of the province is mountainous with abundant land, forest, water and mineral resources, with 90% of Vietnam's coal output extracted from the province. The province is also home to Hạ Long Bay, a World Heritage Site that has 1,969 islands, out of which 989 have been given names.
Phú Yên is a central coastal province in the South Central Coast region, in Central Vietnam. It borders Bình Định to the north, Khánh Hòa to the south, Gia Lai to the northwest, Đắk Lắk to the southwest and the East Sea to the east.
Tiền Giang is a province in the Mekong Delta region of southern Vietnam.
In Vietnam, South Central Coast and South Central Region are two terms which can refer to the same region or two regions that do not correspond to each other. South Central Coast consists of the independent municipality of Đà Nẵng and seven other provinces, which means South Central Coast doesn't include Central Highlands. Nevertheless, the term "South Central Region" can also be used to include Central Highlands as it is part of southern part of Central Vietnam.
The Red River Delta or Hong River Delta is the flat low-lying plain formed by the Red River and its distributaries merging with the Thái Bình River in northern Vietnam. Hồng (紅) is a Sino-Vietnamese word for "red" or "crimson". The delta has the smallest area but highest population and population density of all regions. The region, measuring some 15,000 square kilometres (6,000 sq mi) is well protected by a network of dikes. It is an agriculturally rich and densely populated area. Most of the land is devoted to rice cultivation.
Northern Vietnam, Central Vietnam and Southern Vietnam are the three main historical, geographical and cultural regions within Vietnam. Each region consists of subregions, with considerable cultural differences originating from each subregions.
Northern Vietnam is one of three geographical regions within Vietnam. It consists of three administrative regions: the Northwest, the Northeast, and the Red River Delta. It has a total area of about 109,942.9 km2. Tonkin is a historical exonym for this region plus the Thanh-Nghệ region.
Southern Vietnam is one of the three geographical regions of Vietnam, the other two being Northern and Central Vietnam. It includes 2 administrative regions, which in turn are divided into 19 First Tier units, of which 17 are provinces and 2 are municipalities. In a sub-context, "Southern Vietnam" may include part of Central Vietnam, the two south central costal provinces Ninh Thuận and Bình Thuận are sometimes seen as part of the Southeast region, the Southern. Known as Nam Bộ today in Vietnamese, it was historically called as Gia Định (1779–1832), Nam Kỳ (1832–1945), Nam Bộ (1945–48), and Nam Phần (1948–75).
The following outline is provided as an overview of and topical guide to Vietnam:
Vietnam has a monsoon-influenced climate typical of that of mainland Southeast Asia. The diverse topography, long latitude, and influences from the South China Sea lead to climatic conditions varying significantly between regions. The northern region experiences a monsoonal and temperate climate (Cfa) with four distinct seasons with winters typically dry and summers ranging from hot to mild. In southern and central areas, the climate is tropical monsoon (Aw) with only two seasons. In addition, a temperate climate exists in mountainous areas, which are found in Sa Pa and Da Lat, while a more continental climate exists in Lai Châu Province and Sơn La Province.
Rice production in Vietnam in the Mekong and Red River deltas is important to the food supply in the country and national economy. Vietnam is one of the world's richest agricultural regions and is the second-largest exporter worldwide and the world's seventh-largest consumer of rice. The Mekong Delta is the heart of the rice-producing region of the country where water, boats, houses and markets coexist to produce a generous harvest of rice. Vietnam's land area of 33 million ha, has three ecosystems that dictate rice culture. These are the southern delta, the northern delta and the highlands of the north. The most prominent irrigated rice system is the Mekong Delta. Rice is a staple of the national diet and is seen as a "gift from God".
Vietnam is divided into 63 provinces and cities, with 5 cities and 58 provinces. It is a unitary state, so there is no such thing as a state or self-governing provinces.
