Territorial disputes in the South China Sea
Overlapping claims by China, Taiwan, Vietnam, the Philippines, Malaysia, and Brunei to islands, reefs, and maritime zones in the South China Sea.
United Nations Convention on the Law of the Sea: The international treaty that establishes rules for maritime zones, navigation, and ocean-resource rights. Its maritime-zone rules shape which waters coastal states can claim, but do not settle sovereignty over land features.
Spratly Islands: A group of islands, reefs, and shoals in the southern South China Sea claimed in whole or part by several governments. They are the most widely contested cluster of features in the disputes.
China: A state in East Asia and a major regional and global power. China asserts extensive claims and controls several disputed South China Sea features.
South China Sea: A marginal sea of the western Pacific Ocean bordered by East and Southeast Asian states. Its geography concentrates overlapping claims, shipping routes, and competition for marine resources.
Nine-dash line: A line on Chinese maps enclosing much of the South China Sea, associated with China’s broad claims there. It is the most prominent expression of China’s disputed historical-rights claim.
Paracel Islands: A group of islands in the northern South China Sea controlled by China and claimed by Vietnam and Taiwan. Their competing claims and history of armed confrontation make them a distinct flashpoint.
Vietnam: A state in Southeast Asia whose eastern coast borders the South China Sea. Vietnam contests China’s claims and asserts sovereignty over the Paracel and Spratly Islands.
South China Sea arbitration ruling: A 2016 arbitral award that rejected the legal basis for certain Chinese historic-rights claims under the law of the sea treaty. The ruling clarified maritime entitlements but did not resolve sovereignty over disputed features.
Exclusive economic zone: A maritime zone extending up to 200 nautical miles from a coast, where a state has specified resource rights. Overlapping zones create competing rights to fisheries and seabed resources.
Scarborough Shoal: A ring-shaped reef in the eastern South China Sea claimed by China, the Philippines, and Taiwan. The 2012 standoff between China and the Philippines made it a focal point of their dispute.
