In the early 1970s, the North Vietnamese leaders resorted to various methods of forced assimilation. At first, they sought to pressure ethnic Chinese to adopt Vietnamese citizenship, but only a handful of Hoa cadres complied, most of whom were heavily assimilated individuals anyway. Thereupon the authorities attempted to seize the Chinese passports of the ethnic Chinese under various pretexts, but most Hoa refused to give up their passports.
