Cambodia’s prime minister says he will resist a demand by the U.S. government that Cambodia repay a 50-year-old loan to a government that came to power through a U.S.-backed coup. Prime Minister Hun Sen said this month the U.S. is pressuring the International Monetary Fund to withhold loans to Cambodia unless it repays approximately $500 million in U.S. loans paid to the Lon Nol dictatorship, which used the money to buy weapons it used to kill its own citizens. The loans came as the U.S. government dropped 500,000 tons of explosives on Cambodia as part of President Richard Nixon’s escalation of the Vietnam War.
