The French system of administering the Chinese Cambodian community was terminated in 1958. During the 1960s, Chinese community affairs tended to be handled, at least in Phnom Penh, by the Chinese Hospital Committee, an organization set up to fund and to administer a hospital established earlier for the Chinese community. This committee was the largest association of Chinese merchants in the country, and it was required by the organization’s constitution to include on its fifteen-member board six people from the Teochiu dialect group, three from the Cantonese, two from the Hokkien, two from the Hakka, and two from the Hainanese. The hospital board constituted the recognized leadership of Phnom Penh’s Chinese community. Local Chinese school boards in the smaller cities and towns often served a similar function.
In 1971 the government authorized the formation of a new body, the Federated Association of Chinese of Cambodia, which was the first organization to embrace all of Cambodia’s resident Chinese. According to its statutes, the federation was designed to “aid Chinese nationals in the social, cultural, public health, and medical fields,” to administer the property owned jointly by the Chinese community in Phnom Penh and elsewhere, and to promote friendly relations between Cambodians and Chinese. With leadership that could be expected to include the recognized leaders of the national Chinese community, the federation was believed likely to continue the trend, evident since the early 1960s, to transcend dialect group allegiance in many aspects of its social, political, and economic programs.
Generally, relations between the Chinese and the ethnic Khmer were good. There was some intermarriage, and a sizable proportion of the population in Cambodia was part Sino-Khmer, who were assimilated easily into either the Chinese or the Khmer community. Willmott assumes that a Sino-Khmer elite dominated commerce in Cambodia from the time of independence well into the era of the Khmer Republic.
