Sino-Vietnamese War

The Sino-Vietnamese War was a brief conflict in 1979 between China and Vietnam, primarily triggered by Vietnam's invasion of Cambodia to oust the Khmer Rouge, who had been backed by China. China responded with a military invasion into northern Vietnam, aiming to punish Vietnam and assert its influence. The war lasted about a month, resulting in casualties on both sides and a continued period of tension. It was driven by geopolitical, territorial, and ideological factors, reflecting regional power struggles during the Cold War era. The conflict underscored complex relations between the two communist neighbors.
