Unlike that of Argentina and other Latin American countries, the overseas Chinese population of Cuba was once large, but the now-diminished Chinese Cuban community is today clustered around the largely dying Barrio Chino — called Barrio Chino de La Habana — on Calle Zanja, in Havana. After the Cuban Revolution of 1959, many Chinese Cuban entrepreneurs fled the country for the United States. Since the 1960s, Cuba has not attracted very many, if any, Chinese immigrants (developments or redevelopments of Chinatowns tend to require much private investments for which political conditions in Cuba are not favorable).
