The Third Indochina War was a series of interconnected military conflicts, mainly among the various communist factions over strategic influence in Indochina after Communist victory in South Vietnam, Laos, and Cambodia in 1975.[5][6] The conflict primarily started due to continued raids and incursions by the Khmer Rouge into Vietnamese territory that they sought to retake. These incursions would result in the Cambodian–Vietnamese War in which the newly unified Vietnam overthrew the Pol Pot regime and the Khmer Rouge, in turn ending the Cambodian genocide. Vietnam had installed a government led by many opponents of Pol Pot, most notably Hun Sen, a former Khmer Rouge commander. This led to Vietnam's occupation of Cambodia for over a decade. The Vietnamese push to completely destroy the Khmer Rouge led to them conducting border raids in Thailand against those who had provided sanctuary.[7][8]
Vietnam-China relations became tense because Vietnam chose to be pro-Soviet after unification in 1976 instead of being neutral as before. China strongly objected to the invasion of Cambodia. Chinese armed forces launched a punitive operation (Sino-Vietnamese War) in February 1979 and attacked Vietnam's northern provinces, determined to contain Soviet/Vietnamese influence and prevent territorial gains in the region.[9][10]
In order to acquire full control over Cambodia the People's Army of Vietnam needed to dislodge the remaining Khmer Rouge leaders and units, which had retreated to the remote areas along the Thai-Cambodian border.[11] After the Paris Peace Conference in 1989, the PAVN withdrew from Cambodian territory. Finally regular troop engagements in the region ended after the conclusion of the 1991 Paris Peace Accords.[3][2]
In Laos, an insurgency is still ongoing, though to a lesser extent since 2007, with the government being supported by both China and Vietnam.
