Triton Island (Chinese: 中建岛; pinyin: Zhōngjiàn Dǎo; Vietnamese: đảo Tri Tôn) is one of the islands of Paracel Islands in South China Sea, with an area of 1.2 km². It is also historically known as Bànlù Zhì (Chinese: 半路峙; literally: "halfway tower") or Luó Dǎo (Chinese: 螺岛; literally: "trochus niloticus island") to Chinese fishermen. The current Chinese name of the island is named after the Republic of China Navy warship ROCS Chung-chien (中建號) sent in 1946 to claim the Paracel Islands. The island is administrated by the People's Republic of China but is also claimed by the Republic of China (Taiwan) and Vietnam.
The People's Republic of China's claim on the island is defined as per the Declaration of the Government of the People's Republic of China on the Baselines of the Territorial Sea (May 15, 1996). According to the PRC, the seven points on Zhongjiandao (Triton Island) are the baseline points of the Chinese territorial sea:
