Chinese Cambodians are Cambodian people of Chinese or partial Chinese descent. The Khmer term Khmer kat Chen is used for peoples of mixed Cambodian & Chinese descent while Khmer Chen can mean Cambodian born citizens of Chinese ancestry (Khmer is the majority ethnic group of Cambodia and Chen means "Chinese" in the Khmer language). During the late 1960s and early 1970s, they were the largest ethnic minority in Cambodia; there were an estimated 425,000. However, by 1984, there were only 61,400 Cambodians of Chinese ancestry left. This has been attributed to a combination of warfare, economic stagnation, Khmer Rouge and Vietnamese persecution, and emigration. There are, however, tens of thousands of mixed Chinese and Khmer ancestry.
