Democratic Kampuchea was overthrown by the Vietnamese army in January 1979, and the Khmer Rouge fled to Thailand. However, to counter the power of the Soviet Union and Vietnam, a group of countries including China, the United States, Thailand as well as some Western countries supported the Khmer Rouge-dominated Coalition Government of Democratic Kampuchea to continue holding Cambodia's seat in the United Nations, which was held until 1993, after the Cold War had ended. China has defended its ties with the Khmer Rouge. Chinese Foreign Ministry spokeswoman Jiang Yu said that "the government of Democratic Kampuchea had a legal seat at the United Nations, and had established broad foreign relations with more than 70 countries".
