iron and wrecked military vehicles to manufacture their own bullets and mines. The statement made it clear that the policy of self-reliance would continue in peacetime. In another move aimed at reducing foreign influence on the country, the regime announced on May 10 that it would not allow foreigners to remain in Cambodia but that the measure was only temporary; and it added, "We shall reconsider the question [of allowing foreigners to enter the country] after the re-establishment of diplomatic, economic and commercial relations with other countries." Although Cambodia resumed diplomatic relations with a number of nations, the new government informed the UN General Assembly on October 6, 1975, that it was neutral and economically self-sufficient and would not ask for aid from any country. On September 9, however, the Chinese ambassador arrived in Cambodia, and there were soon reports that China was providing aid to the Khmer Rouge. Estimates of the number of Chinese experts in Cambodia after that time ranged from 500 to 2,000. The policy of self-reliance also meant that the government organized the entire population into forced-labor groups to work in paddies and on other land to help the country reach its goal of food self-sufficiency. The Khmer Rouge, as soon as it took power on April 17, 1975, emptied Phnom Penh (of its approximately 2 million residents) as well as other cities and towns, and forced the people into the countryside. This overnight evacuation was motivated by the urgent need to rebuild the country's war-torn economy and by the Khmer Rouge peasantry's hostility toward the cities. According to a Khmer Rouge spokesman at the French embassy on May 10, the evacuation was necessary to "revolutionize" and to "purify" the urban residents and to annihilate Phnom Penh, which "Cambodian peasants regarded as a satellite of foreigners, first French, and then American, and which has been built with their sweat without bringing them anything in exchange." The only people who were not ordered to leave the city were those who operated essential public services, such as water and electricity. Other Khmer Rouge leaders rationalized the evacuation as a matter of self-reliance. They told the Swedish ambassador in early 1976 that "they didn't have any transportation facilities to bring food to the people, and so the logical thing was to bring the people to the food, i.e., to evacuate them all and make them get out into the
