Putin, Pol Pot was the leader of the Marxist/Maoist/Communist Party, and under his control, this is what happened in Cambodia:
"The Khmer Rouge also classified people by religion and ethnic group. They banned all religion and dispersed minority groups, forbidding them to speak their languages or to practice their customs. They especially targeted Buddhist monks, Muslims, Christians, Western-educated intellectuals, educated people in general, people who had contact with Western countries or with Vietnam, disabled people, and the ethnic Chinese, Laotians and Vietnamese. Some were put in the S-21 camp for interrogation involving torture in cases where a confession was useful to the government. Many others were summarily executed. Confessions forced at S-21 were extracted from prisoners through such methods as raising prisoners by their arms tied behind and dislocating shoulders, removing toenails with pliers, suffocating a prisoner repeatedly and skinning a person while alive.[18]
According to François Ponchaud's book Cambodia: Year Zero, "Ever since 1972, the guerrilla fighters had been sending all the inhabitants of the villages and towns they occupied into the forest to live and often burning their homes, so that they would have nothing to come back to." The Khmer Rouge refused offers of humanitarian aid, a decision that caused a humanitarian catastrophe: millions died of starvation and brutal government-inflicted overwork in the countryside. To the Khmer Rouge, outside aid went against their principle of national self-reliance.
Property became collective, and education was dispensed at communal schools. Children were raised on a communal basis. Even meals were prepared and eaten communally. Pol Pot's regime was extremely paranoid. Political dissent and opposition was not permitted. People were treated as opponents based on their appearance or background. Torture was widespread, thousands of politicians and bureaucrats accused of association with previous governments were executed. Phnom Penh was turned into a ghost city, while people in the countryside were dying of starvation, illnesses, or simply killed."
