Pol Pot
According to journalist Elizabeth Becker, former U.S. National Security Advisor Zbigniew Brzezinski said that in 1979, "I encouraged the Chinese to support Pol Pot. Pol Pot was an abomination. We could never support him, but China could." Brzezinski has denied this, writing that the Chinese were aiding Pol Pot "without any help or encouragement from the United States."
