In the aftermath of the Sino-Vietnam War, both China and Vietnam assert claims of victory. During the conflict, Chinese troops briefly entered Vietnamese territory along the China-Vietnam border, but they subsequently withdrew. Vietnam maintained control over Cambodia until 1989. In response to the tensions, Vietnamese authorities increased the expulsion of overseas Chinese residents. The border clashes between China and Vietnam persisted until 1991, creating a prolonged period of contention between the two nations. As such, the question of who emerged as the definitive victor in the Sino-Vietnam War remains complex, with both sides maintaining their respective claims.
