Hainan Island incident

A ten-day international incident between the United States and the People's Republic of China (PRC) resulted from a mid-air collision between a United States Navy EP-3E ARIES II signals intelligence aircraft and a People's Liberation Army Air Force J-8 interceptor on April 1, 2001.

The EP-3 was flying over the South China Sea at a point roughly midway between Hainan Island and the Paracel Islands when it was intercepted by two J-8II fighters. A collision between the EP-3 and one of the J-8s caused damage to the EP-3 and the loss of the J-8 and its pilot. The EP-3 was forced to make an emergency landing on Hainan without permission from the PRC, and its 24 crew members were detained and interrogated by Chinese authorities until a statement was delivered by the United States government regarding the incident. The ambiguous phrasing of the statement allowed both countries to save face and defused a potentially volatile situation.

Background

This sea area includes the South China Sea Islands, which are claimed by the PRC and several other countries. It is a strategically sensitive area.

The United States and the People's Republic of China disagree on the legality of the overflights by US naval aircraft of the area where the incident occurred. This part of the South China Sea comprises part of the PRC's exclusive economic zone based on the United Nations Convention on the Law of the Sea (UNCLOS) and the Chinese claim that the Paracel Islands belong to China. This claim was acknowledged by Vietnam in 1958 but it has since reversed itself to contest the claim after the end of the Vietnam War in 1975. The United States remains neutral in this dispute, but patrols the sea regularly with naval ships and airplanes, during what it terms freedom of navigation operations. The PRC interprets the convention as allowing it to preclude other nations' military operations within this area, but the United States does not recognize China's claim for the Paracel Islands and maintains that the Convention grants free navigation for all countries' aircraft and ships, including military aircraft and ships, within a country's exclusive economic zone. Although the United States is not party to UNCLOS, it has accepted and complies with nearly all of the treaty's provisions.

A PRC Sukhoi Su-27 force is based at Hainan. The island also houses a large signals intelligence facility that tracks civil and military activity in the area and monitors traffic from commercial communications satellites. The United States has long kept the island under surveillance; on May 22, 1951, for example, RAF Spitfire PR Mk 19s based at Hong Kong's Kai Tak Airport flew photo-reconnaissance missions at the behest of US naval intelligence.
