Cambodia-Vietnam War


Cambodia-Vietnam War (1977-1991)-- During their war against the U.S.-sponsored regimes in Saigon and Phnom Penh, the North Vietnamese and the Khmer Rouge were able to mask their ideological differences and ignore the historical hostility between their two peoples. After taking power though, these differences turned violent. Beginning with low-level cross-border raids and escalating into full-fledged war in late December of 1978 when Vietnam launched a massive conventional invasion of Cambodia, swiftly occupying the nation within days.

Vietnam set up a new government in Phnom Penh with Khmer Rouge defectors but found itself immersed in a long and difficult war of occupation as the Khmer Rouge returned to the guerrilla warfare they knew so well. Vietnamese troops left after more than a decade, with the friendly government of Heng Samrin in control of most of Cambodia.
