The Hoa people are the citizens and nationals of Vietnam of full or partial Han Chinese ancestry. Chinese migration into Vietnam dates back millennia but allusions to the contemporary Hoa today mostly refers to people of Chinese ancestry who immigrated to Vietnam during the 18th century, who especially trace their ancestry to various southern Chinese provinces. The Hoa are an ethnic minority group in Vietnam as part of the Chinese community there, and can also be found in other regions such as in the Americas. They may also be called "Chinese-Vietnamese" or "Chinese people living in/from Vietnam" by the Vietnamese.

The Sino-Vietnamese War was a brief conflict that occurred in early 1979 between China and Vietnam. China launched an offensive in response to Vietnam's invasion and occupation of Cambodia in 1978, which ended the rule of the Chinese-backed Khmer Rouge. The conflict lasted for about a month, with China withdrawing its troops in March 1979.
