Chai Zemin was born in October 1916 in an ordinary family in Wenxi, Shanxi. After he graduated from high school, be became politically active and joined the Communist Party of China. Chai's career as a diplomat started in December 1960 when he entered the Ministry of Foreign Affairs of China. He was appointed China's ambassador to Hungary in 1961, to Guinea in 1964, and to Egypt in 1970. In 1975, China and Thailand established diplomatic relations, and Chai became the first China's ambassador to Thailand. During his two-and-half-year term in Thailand, he experienced two general elections, three coups d'état, four different prime ministers and five different governments in the country. It had been a great challenge for him to work in such a turbulent environment, and the King of Thailand awarded him a White Elephant Medal for his diplomatic achievement. In the summer of 1978, China and the United States started negotiations on normalizing relations between the two countries, and Chai Zemin took the position of director in the People's Republic of China Liaison Office in Washington, D.C. and participated in the negotiations. It was agreed at the end of 1978 that China and the United States would officially establish relations on January 1, 1979 and set up embassies and appoint ambassadors to each other's country. Chai thus became the first China's ambassador to the United States thirty years after the founding of the People's Republic of China. In the fall of 1981, the Michigan State University conferred an honorary degree of Doctor of Laws on Chai for his contributions to the China–US relations. In 1983, Chai Zeming left his ambassador position and assumed the title of vice director of the Chinese Foreign Affairs Society, and had since been a member of the Chinese People's Political Consultative Conference for three terms. In early 1990s, Chai resigned his position at the Chinese Foreign Affairs Society, and afterwards, he became director and consultant of a number of other societies and organizations.
