The first island chain refers to the first chain of major Pacific archipelagos out from the East Asian continental mainland coast. It is principally composed of the Kuril Islands, the Japanese archipelago, the Ryukyu Islands, Taiwan (Formosa), the northern Philippines, and Borneo, hence extending all the way from the Kamchatka Peninsula in the northeast to the Malay Peninsula in the southwest. The first island chain forms one of three island chain doctrines within the island chain strategy in the U.S. foreign policy. [1] [2]
Much of the first island chain is roughly situated in waters claimed by China. [3] These include the South China Sea, within the nine-dash line, as well as the East China Sea west of the Okinawa Trough.
According to a 2018 United States Department of Defense report to Congress, the People's Liberation Army's Anti-Access/Area Denial military capabilities aimed at the first island chain are its most robust. [4] The report also stated that the People's Liberation Army Navy's ability to perform missions beyond the first island chain is "modest but growing as it gains experience operating in distant waters and acquires larger and more advanced platforms." [4]
Around 2009 Japanese military strategist Toshi Yoshihara and Naval War College professor James R. Holmes suggested the American military could exploit the geography of the first island chain to counter the People's Liberation Army Navy build-up. [5] The Cabinet of Japan has also passed defense white papers emphasizing the threat posed by the People's Liberation Army Navy in the first island chain. [6] [7] [8]
In the later years of the 2010s, Japan started deploying military assets to Yonaguni and its other islands to counter China's presence along that area of the first island chain. [9] [10]
Japan's strategic position in the first island chain began with US-Japan joint efforts to counter Soviet expansion. The Japan Self-Defense Forces currently plays the role of protecting US military bases and preserving military strength in East Asia. As for Japan's Territorial Protection Self-Defense Forces, which mainly rely on islands in southern Japan adjacent to the Yellow Sea and the East China Sea, Japan has military advantages in anti-submarine, air defense and sea mine technologies. [11]
In 2021, Lloyd Austin, on behalf of the United States, thanked his counterpart in the Philippines Delfin Lorenzana for retaining the 70-year-old visiting forces agreement between the two nations. [12] In 2023 four new bases were announced in the Philippines. [13]
In the First Island Chain, Taiwan is considered of critical strategic importance. [14] It is located at the midpoint of the first chain and occupies a strategic position. [14]
U.S. General Douglas MacArthur pointed out that before World War II, the US protected its western shores with a line of defense from Hawaii, Guam, to the Philippines. However, this line of defense was attacked by Japan with the Pearl Harbor bombing of 1941, thereby drawing the U.S. into the war. The US subsequently launched the air Raid on Taipei (called Taihoku under Japan's empire) and launched the atomic bombings of Hiroshima and Nagasaki. The WW2 victory allowed the US to expand its line of defense further west to the coast of Asia, and thus the US controlled the first island chain. [15] Between the end of WW2 and the Korean War, MacArthur praised Taiwan, located at the midpoint of the first island chain, as an 'unsinkable aircraft carrier'. [16]
In April 2014, the United States Naval Institute (USNI) assessed that the first island chain is the most effective point to counter any Chinese invasion. [17] The US could not only cut off the People's Liberation Army Navy from entering the western Pacific, but also predict where they may move before trying to break through in the first place. The US and first island chain countries are able to coordinate because of the US military's freedom of navigation in the first chain block. [18] A June 2019 article published by the United States Naval Institute (USNI) called for the navy to establish and maintain a blockade around the first island chain if the US was go to war with China. [17]
Andrew Krepinevich argued that an "archipelagic defense" of the countries that make up the first island chain would make up a big part of the implementation of the national defense strategy of 2018. [19] A 2019 report by the Center for Strategic and Budgetary Assessments "proposes a U.S. military strategy of Maritime Pressure and a supporting joint operational concept, “Inside-Out” Defense, to stabilize the military balance in the Western Pacific and deny China the prospect of a successful fait accompli." The first island chain plays a central role in the report. [20] In 2020, the United States Marine Corps started shifting its tactics in conjunction with the United States Navy to be deployed along or near the first island chain. [5] In 2021, the United States Marine Corps announced a goal of three additional Pacific-based regiments. [21] [13]
The People's Liberation Army Navy is the maritime service branch of the People's Liberation Army, and the largest navy per number of ships in the world.
The Republic of China Armed Forces, also known as the ROC Armed Forces are the armed forces of the Republic of China (ROC) that once ruled Mainland China and now currently restricted to its territorial jurisdictions of Taiwan, Penghu, Kinmen and Matsu Islands. They consist of the Army, Navy, Air Force and Military Police Force. The military is under the civilian control of the Ministry of National Defense, a cabinet-level agency overseen by the Legislative Yuan.
The Pacific War, sometimes called the Asia–Pacific War or the Pacific Theater, was the theater of World War II that was fought in eastern Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War.
The First Taiwan Strait Crisis was a brief armed conflict between the People's Republic of China (PRC) and the Republic of China (ROC) in Taiwan. The conflict focused on several groups of islands in the Taiwan Strait that were held by the ROC but were located only a few miles from mainland China.
The United States foreign policy toward the People's Republic of China originated during the Cold War. At that time, the U.S. had a containment policy against communist states. The leaked Pentagon Papers indicated the efforts by the U.S. to contain China through military actions undertaken in the Vietnam War. The containment policy centered around an island chain strategy. President Richard Nixon's China rapprochement signaled a shift in focus to gain leverage in containing the Soviet Union. Formal diplomatic ties between the U.S. and China were established in 1979, and with normalized trade relations since 2000, the U.S. and China have been linked by closer economic ties and more cordial relations. In his first term as U.S. president, Barack Obama said, "We want China to succeed and prosper. It's good for the United States if China continues on the path of development that it's on".
Nanshin-ron was a political doctrine in the Empire of Japan that stated that Southeast Asia and the Pacific Islands were Japan's sphere of interest and that their potential value to the Empire for economic and territorial expansion was greater than elsewhere.
The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng is a two-stage, solid-fuel rocket, single-warhead medium-range ballistic missile in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985–86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually.
China Coast Guard (CCG) is the maritime security, search and rescue, and law enforcement service branch of the People's Armed Police of China.
The Andaman and Nicobar Command (ANC) is a integrated tri-services command of the Indian Armed Forces, based at Port Blair in the Andaman and Nicobar Islands, a Union Territory of India. It was created in 2001 to safeguard India's strategic interests in Southeast Asia and the Strait of Malacca by increasing rapid deployment of military assets in the region. It provides logistical and administrative support to naval ships which are sent on deployment to East Asia and the Pacific Ocean.
The String of Pearls is a geopolitical hypothesis proposed by United States political researchers in 2004. The term refers to the network of Chinese military and commercial facilities and relationships along its sea lines of communication, which extend from the Chinese mainland to Port Sudan in the Horn of Africa. The sea lines run through several major maritime choke points such as the Strait of Mandeb, the Strait of Malacca, the Strait of Hormuz, and the Lombok Strait as well as other strategic maritime centres in Somalia and the littoral South Asian countries of Pakistan, Sri Lanka, Bangladesh, and the Maldives.
U.S. President Barack Obama's East Asia Strategy (2009–2017), also known as the Pivot to Asia, represented a significant shift in the foreign policy of the United States since the 2010s. It shifted the country's focus away from the Middle Eastern and European sphere and allowed it to invest heavily and build relationships in East Asian and Southeast Asian countries, especially countries which are in close proximity to the People's Republic of China (PRC) either economically, geographically or politically to counter its rise as a rival superpower.
AirSea Battle is an integrated battle doctrine that forms a key component of the military strategy of the United States. The doctrine became official in February 2010, and was renamed to Joint Concept for Access and Maneuver in the Global Commons (JAM-GC) in 2015.
Territorial disputes in the South China Sea involve conflicting island and maritime claims in the South China Sea by several sovereign states, namely the People's Republic of China (PRC), Taiwan, Brunei, Malaysia, the Philippines, and Vietnam. The disputes involve the islands, reefs, banks, and other features of the region, including the Spratly Islands, Paracel Islands, Scarborough Shoal, and various boundaries in the Gulf of Tonkin. The waters near the Indonesian Natuna Islands, which some regard as geographically part of the South China Sea, are disputed as well. Maritime disputes also extend beyond the South China Sea, as in the case of the Senkaku Islands and the Socotra Rock, which lie in the East China Sea.
Anti-Access/Area Denial is a military strategy to control access to and within an operating environment. In an early definition, anti-access refers to those actions and capabilities, usually long-range, designed to prevent an opposing force from entering an operational area. Area denial refers to those actions and capabilities, usually of shorter range, designed to limit an opposing force's freedom of action within the operational area. In short, A2 affects movement to a theater, while AD affects movement within a theater. A2/AD typically refers to a strategy used by a weaker opponent to defend against an opponent of superior skill, although a stronger opponent can also use A2/AD.
The Quadrilateral Security Dialogue (QSD), commonly known as the Quad, is a strategic security dialogue between Australia, India, Japan and the United States that is maintained by talks between member countries. The dialogue was initiated in 2007 by Japanese Prime Minister Shinzo Abe, with the support of Australian Prime Minister John Howard, Indian Prime Minister Manmohan Singh and U.S. Vice President Dick Cheney. The dialogue was paralleled by joint military exercises of an unprecedented scale, titled Exercise Malabar. The diplomatic and military arrangement was widely viewed as a response to increased Chinese economic and military power.
The Code for Unplanned Encounters at Sea (CUES) is an agreement reached at the 2014 Western Pacific Naval Symposium to reduce the chance of an incident at sea between the countries in the agreement, and — in the event that one occurs — to prevent it from escalating. Twenty one countries have joined the agreement, including Australia, Brunei, Cambodia, Canada, Chile, China, France, Indonesia, Japan, Malaysia, New Zealand, Papua New Guinea, Peru, the Philippines, Russia, Singapore, South Korea, Thailand, Tonga, the United States and Vietnam. Taiwan, a non-signatory state also reportedly implements the agreement.
The island chain strategy is a strategic maritime containment plan first conceived by American foreign policy statesman John Foster Dulles in 1951, during the Korean War. It proposed surrounding the Soviet Union and China with naval bases in the West Pacific to project power and restrict sea access.
United States–China security cooperation refers to various projects, combined operations, communications, official dialogues, joint exchanges, and joint exercises, between agencies, groups, and individuals within the government of United States and the People's Republic of China, in a number of areas pertaining to global security, defense policy, and various forms of military and security cooperation.
Geostrategy in Taiwan refers to the foreign relations of Taiwan in the context of the geography of Taiwan. Taiwan is an island country in East Asia, while it is also located at the center of the first island chain and commands the busy traffic of Taiwan Strait and Bashi Channel.
Cabbage tactics is a militarily swarming and overwhelming tactic used by the People's Liberation Army Navy to seize control of islands. It is done by surrounding and wrapping the island in successive layers of Chinese naval ships, China Coast Guard ships, and fishing boats and cut off the island from outside support.
