The Chinese, in addition to having their livelihood eradicated on the whole, also suffered because of their socioeconomic class. They were mainly well-educated urban merchants, and thus were characteristic of the people whom the Khmer Rouge detested. Chinese refugees have reported that they shared the same brutal treatment as other urban Cambodians under the Khmer Rouge régime but they were not discriminated against as an ethnic group until after the Vietnamese invasion due to the PRC's support of the Khmer Rouge. Several of the most senior members of the Khmer Rouge were themselves of partial Chinese descent, such as Nuon Chea, Ieng Sary, Khieu Samphan, Kang Kek Iew, Son Sen, Ta Mok and even Pol Pot himself. King Sihanouk saw the delineation and repression of Chinese business and identity as nationalism emerged and the Chinese were perceived as threatening to Cambodian sovereignty. During the various regimes between 1970 and 1990, Chinese enterprise and cultural expression was completely banned and destroyed and many ethnic Chinese died or fled the country.
