The Taiwan Waterway, commonly known as the Formosa Waterway, is a 180-kilometer strait connecting Taiwan and mainland China.
The strait is currently a portion of the South China Sea, and it connects to the East China Sea to the north.
Asia's continental shelf surrounds the whole strait, with the narrowest point measuring 130 kilometres.
The People's Republic of China (PRC) and Taiwan have long supported the One-China Policy, which considers the Taiwan Strait to be part of a single "China's" exclusive economic zone.
