A Line in the Sand A Historical Review and Reconsideration of the Post-War Sino-Vietnamese Land Bord

A Historical Review and Reconsideration of the Post-War Sino-Vietnamese Land Border Issue This paper, through an in-depth examination of newly available documents, systematically investigates the evolution and underlying causes of the Sino-Vietnamese land border conflicts after World War II. The author argues that the escalation of border tensions was not merely a territorial dispute; in essence, it reflected profound divergences between China and Vietnam over their respective national strategic security interests, particularly the geopolitical threat posed to China when Vietnam aligned itself with the Soviet Union in the late 1970s. The paper meticulously traces the dynamic process from the legacy of border demarcation in the late Qing Dynasty, through the 1979 Sino-Vietnamese War, to the final resolution of the issue through diplomatic negotiations in the 1990s. The author emphasizes that the land border was long regarded by Vietnam as a strategic bargaining chip in its negotiations with China over sovereignty in the South China Sea and the demarcation of the Beibu Gulf. Its ultimate settlement resulted from both sides returning to a balance of national interests as sovereign states. Ultimately, through historical reflection, this paper aims to reveal how geopolitics and ideology have intertwined to shape the trajectory of contemporary Sino-Vietnamese relations. AI-generated map.
