Answer: China and Vietnam
Notes: Vietnam’s foreign ministry recently published a map defining its claim in the Gulf of Tonkin. The Gulf of Tonkin is also called “Beibu Gulf” in Chinese and “Bac Bo Gulf” in Vietnamese. It is a shallow, semi-enclosed water body in the northwestern South China Sea. It is bordered by Vietnam’s northern coast, China’s Guangxi region, the Leizhou Peninsula, and Hainan Island. It connects to the South China Sea via its southern mouth and the Hainan Strait in the northeast. Major ports include Haiphong and Ben Thuy in Vietnam and Beihai in China.
