gulf of tonkin

The Gulf of Tonkin (480 kmx240 km) lies between Vietnam and China. Notably shallow (less than 60 meters deep), it is the northwest arm of the South China Sea. The Red River flows into the Gulf. Haiphong, Vietnam, and Beihai, China, are the chief ports. The Chinese Hainan Island lies in the Gulf. Other small islands in the gulf include:

Weizhou, China

The Gulf is notable in history because of events in August of 1964 that led to the open involvement of the United States in the Vietnam War, with the Gulf of Tonkin Resolution. Because in several Asian languages, "Tonkin" means both Tonkin and Tokyo, Vietnamese call it the Vịnh Bắc Bộ ("Bac Bo Gulf"; "Gulf/Bay of the North"). Modern Chinese geographers use this convention as well, calling it the Beibu Gulf (北部灣, bɐk1bəʊ6wɑn1 in Cantonese).
