After the fall of the Pol Pot regime of Democratic Kampuchea, Cambodia was under Vietnamese occupation and a pro-Hanoi government, the People's Republic of Kampuchea, was established. A civil war raged during the 1980s opposing the government's Kampuchean People's Revolutionary Armed Forces against the Coalition Government of Democratic Kampuchea, a government in exile composed of three Cambodian political factions: Prince Norodom Sihanouk's FUNCINPEC party, the Party of Democratic Kampuchea and the Khmer People's National Liberation Front (KPNLF).

The Coalition Government of Democratic Kampuchea, renamed in 1990 to the National Government of Cambodia, was a coalition government in exile composed of three Cambodian political factions, namely Prince Norodom Sihanouk's FUNCINPEC party, the Party of Democratic Kampuchea and the Khmer People's National Liberation Front (KPNLF) formed in 1982, broadening the de facto deposed Democratic Kampuchea regime. For most of its existence, it was the internationally recognized government of Cambodia.
