At a party plenum in 1930, the Indochinese Communist Party made a statement that the Chinese were to be treated on an equal footing with the Vietnamese, specifically defining them as "The workers and labourers among the Chinese nationals are allies of the Vietnamese revolution". One year after the state of North Vietnam was established, a mutual agreement was made between the Communist Party of China and Communist Party of Vietnam to give ethnic Chinese living in North Vietnam Vietnamese citizenship. This process was completed by the end of the 1950s.
