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).

Cambodia, officially the Kingdom of Cambodia, is a country in Southeast Asia on the Indochinese Peninsula, spanning an area of 181,035 square kilometres, bordered by Thailand to the northwest, Laos to the north, Vietnam to the east, and the Gulf of Thailand to the southwest. The capital and most populous city is Phnom Penh.
