When the Vietnamese leaders launched their invasion of Kampuchea to remove the Khmer Rouge government in 1978, they did not expect a negative reaction from the international community. However, the events that followed the invasion showed that they had severely miscalculated international sympathies toward their cause. Instead of backing Vietnam, most United Nations member countries denounced the Vietnamese use of force against Kampuchea, and even moved to revive the battered Khmer Rouge organisation that had once governed the country with such brutality. Thus, Kampuchea became more than just a military problem for Vietnam, quickly evolving into an economic and diplomatic problem in the international arena. Throughout the decade in which Vietnam occupied neighbouring Kampuchea, the Vietnamese Government, and the PRK government which it installed, were placed on the periphery of the international community.
