The East China Sea is a marginal sea east of China, a part of the Pacific Ocean and covers an area of 1,249,000 square kilometres. The East China Sea is bounded on the east by Kyūshū and the Ryukyu Islands of Japan, on the south by the island of Taiwan, and on the west by mainland China and the Asian continent. It is connected with the South China Sea by the Taiwan Strait and with the Sea of Japan by the Korea Strait; it opens in the north to the Yellow Sea. It is also the place of disputes between the People's Republic of China, Japan, and South Korea over the extent of their respective exclusive economic zones and the possession of the Senkaku (also known as Diaoyu in China) Islands.
