Article 9 of the Nationality Law of the People's Republic of China indicates that: "Any Chinese national who has settled abroad and who has been naturalized there or has acquired foreign nationality of his own free will automatically loses [sic] Chinese nationality" (The Nationality Law).

According to the Embassy of the People's Republic of China in Ottawa (phone conversation of 16 July 1990), there is no time limit put on the loss of Chinese citizenship. If a Chinese citizen acquires other citizenship, however, Chinese citizenship is lost; if a Chinese citizen is without a valid passport, Chinese citizenship may be denied. No corroboration of this information was found in the public sources currently available to the IRBDC in Ottawa.
