A significant Chinese presence in Tonga is relatively recent. There were approximately three or four thousand Chinese people living in Tonga in 2001, thus comprising 3 or 4% of the total Tongan population. This figure includes Tongan citizens of Chinese ethnicity, and marks a sharp increase from the 1996 census, which recorded only 55 persons on Chinese ethnicity living in Tonga. Chinese in Tonga and Chinese Tongans are Tonga's main ethnic minority group, and have been subjected to significant levels of racism, including racist violence, in recent years.
