China Sea is the name of two seas of the Pacific Ocean along the east coast of Asia.
These conflicts included the Battle of Okinawa in 1945. Shanghai, China, and Nagasaki, Japan, are the main ports of the sea. The South China Sea includes the Gulf of Tonkin and Gulf of Thailand on the west and Manila Bay on the east. Violent tropical storms called typhoons sweep over the sea. David A.
