Cambodia’s King Norodom Sihamoni has put into effect a treaty that would complete the demarcation line between Cambodia and neighboring Vietnam, drawing criticism from opponents of Prime Minister Hun Sen who say the move violates the country’s sovereignty.
The supplementary treaty of 2019 on border posts was signed by Hun Sen and his Vietnamese counterpart Nguyen Xuan Phuc in early October. It recognizes the legality of two documents, a 1985 supplemental protocol and a 2005 agreement on border demarcation, thereby solidifying the demarcation of 84% of the border.
The promulgation of the treaty was made through a royal decree on December 5, 2019, and the law was published Friday. The king signed the treaty at the request of Hun Sen.
