East China Sea, arm of the Pacific Ocean, c.480,000 sq mi (1,243,200 sq km), bounded on the E by the Kyushu and Ryukyu islands, on the S by Taiwan, and on the W by China. 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 N to the Yellow Sea. The Chang River empties into the sea, whose main ports are Shanghai, Hangzhou, Ningbo, and Fuzhou, China; and Chilung, Taiwan. Territorial control of much of the eastern half of the sea (and its oil and gas) is disputed between China and Japan.
