The coast guards of Vietnam and China on May 22 conducted their joint patrol in the northern Gulf of Tonkin, covering the waters off Mong Cai city in Quang Ninh province and Dongxing and Fangchenggang cities in China's Guangxi province. The joint patrol, the second of its kind this year, spanned 102 nautical miles from Point 1 to Point 9 along the countries' demarcation line in the Gulf of Tonkin. This area is a bustling zone for bilateral import-export and goods exchange activities. It is also a hotspot for illegal activities such as smuggling, trade fraud, illegal border crossings, and unauthorised maritime entries. Source: Vietnam News Agency
