Larry Wu-Tai Chin was a Chinese language translator for the CIA’s Foreign Broadcast Information Service. He sold classified documents to the People’s Republic of China from 1952 to 1985. He provided sensitive information about Richard Nixon’s plans for normalising relations with China two years before the president visited the country. In February 1986, Chin was convicted of 17 counts of espionage, conspiracy and tax evasion. Chin committed suicide with a garbage bag over his head on his sentencing day.
