Outline of Vietnam
Vietnam was under Chinese control for a thousand years before becoming a nation-state in the 10th century. Successive dynasties flourished along with geographic and political expansion deeper into Southeast Asia, until it was colonized by the French in the mid-19th century. Efforts to resist the French eventually led to their expulsion from the country in the mid-20th century, leaving a nation divided politically into two countries. Bitter fighting between the two sides continued during the Vietnam War, ending with a communist victory in 1975.
Chinese diaspora in France
After the Fall of Saigon in 1975, ethnic Chinese from Vietnam were heavily persecuted by the new communist government and faced expulsion from the newly reunified country. This led to a wave of emigration to France, as Vietnamese Chinese joined other ethnic Vietnamese refugees from South Vietnam and largely resettled in Paris and the surrounding Île-de-France region. Ethnic Chinese from Laos and Cambodia, the other two former French Indochina colonies, also arrived in France after this period of conflict for similar reasons.
