The Hoa are an overseas Chinese minority in Vietnam. They are also typically referred to as either Chinese Vietnamese, Vietnamese Chinese, Sino-Vietnamese, or ethnic Chinese in/from Vietnam. The Vietnamese government's classification of the Hoa excludes two other groups of Chinese-speaking peoples, the San Diu (mountain Chinese) and the Ngai. Along with ethnic Vietnamese, the Hoa are usually referred to as "Vietnamese" by Chinese from mainland China.According to the 1999 Vietnamese census, with 1.1% of the population, the Hoa are the 6th-largest ethnic group in Vietnam.
