Vietnam's victory was supported by the Soviet Union and had significant ramifications for the region. The People's Republic of China launched a punitive invasion of northern Vietnam but then retreated, with both sides claiming victory. China, the United States and the ASEAN countries sponsored the creation and the military operations of a Cambodian government in exile, known as the Coalition Government of Democratic Kampuchea, which included the Khmer Rouge, the republican Khmer People's National Liberation Front and the royalist Funcinpec Party.
