An Investigation into the Resolution of the Sino-Vietnamese Land Border Issue

The modern Sino-Vietnamese land border dispute began after the signing of the Sino-French New Treaty, in which the Sino-Vietnamese land border was explicitly defined, but because of natural or man-made factors, the boundary markers were displaced. The land boundary dispute between the two countries was the result of the different claims made by the two countries. The two countries negotiated the land border in 1955, when they resolved to set aside the dispute; in 1976, the reunification of Vietnam opened a second border negotiation, but both sides still insisted on their own views, and the negotiation broke down, the impact of this time was to lead to the war between the two countries in 1979; in 1991, the normalization of Sino-Vietnamese relations, the two countries opened a third border negotiation, and the two countries and the two countries signed the Agreement on the Boundary between the People's Republic of China and the Socialist Republic of Vietnam in 1999. In 1991, China and Vietnam normalized their relations, and the two countries started the third border negotiation, and in 1999, the two countries signed the Land Boundary Treaty between the People's Republic of China and the Socialist Republic of Vietnam, to peacefully solve the border disputes, and in 2008, they completed the demarcation of the border as well as the establishment of boundary monuments to define the land border between China and Vietnam.
