Allegations of United States support for the Khmer Rouge

The United States (U.S.) voted for the Khmer Rouge and the Khmer Rouge-dominated Coalition Government of Democratic Kampuchea (CGDK) to retain Cambodia's United Nations (UN) seat until as late as 1993, long after the Khmer Rouge had been mostly deposed by Vietnam during the 1979 Vietnamese invasion of Cambodia and ruled just a small part of the country. It has also been reported that the U.S. encouraged the government of China to provide military support for the Khmer Rouge, a claim which was denied by Zbigniew Brzezinski.
