Chinese Cambodians are Cambodian people of Chinese or partial Chinese descent. The Khmer term Khmer kat Chen (ខ្មែរកាត់ចិន) is used for peoples of mixed Cambodian & Chinese descent while Khmer Chen (ខ្មែរចិន) 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 emigration. There are, however, tens of thousands of mixed Chinese and Khmer ancestry.
