policy of "strict neutrality" and would accept foreign assistance from "all countries which love peace and justice." As early as April 20, 1970, Cambodia formally requested military and economic aid from Washington to help cope with growing war expenditures and with an increasing budgetary deficit. As military activity in the country intensified, the United States became Cambodia's largest donor and supplier. Moscow sent medical equipment and, in October 1971, the Soviets renewed a financial agreement with the republican regime. The Economic Support Fund, to which the United Nations (UN), the United States, Britain, Japan, New Zealand, Thailand, and Malaysia pledged their contributions, provided US$21 million in auxiliary relief. Other nations, including Italy, Israel, West Germany, and Switzerland, provided funds mostly to assist war victims. France earmarked its aid for the maintenance of French educational programs and cultural institutions. Nevertheless, these palliative measures fell far short of what was needed. By 1975 the economy had collapsed, and the country was surviving mainly on imported food financed by the United States government. Under the Khmer Rouge (1975–1979) Under the leadership of the Khmer Rouge, Cambodia underwent a brutal and radical revolution. When the communist forces took power in Phnom Penh in April 1975, their immediate goals were to overhaul the social system and to revitalize the national economy. The economic development strategy of the Khmer Rouge was to build a strong agricultural base supported by local small industries and handicrafts. As explained by Deputy Premier Ieng Sary, the regime was "pursuing radical transformation of the country, with agriculture as the base. With revenues from agriculture we are building industry which is to serve the development of agriculture." This strategy was also the focus of a doctoral thesis written by future Khmer Rouge leader Khieu Samphan at the University of Paris in 1959. Samphan argued that Cambodia could only achieve economic and industrial development by increasing and expanding agricultural production. The new communist government implemented the tenets of this thesis; it called for a total collectivization of agriculture and for a complete nationalization of all sectors of the economy. Strict adherence to the principle of self-reliance constituted the central goal of the Khmer Rouge regime. A Phnom Penh radio broadcast in early May (about a month after the Khmer Rouge arrived in the capital) underscored the importance of Cambodian self- reliance and boasted that during the war the Khmer Rouge had used scrap
