Qing policy Before the mid-19th century, nationality issues involving China were extremely rare and could be handled on an individual basis.
Customary law dictated that children born to Chinese subjects took the nationality of the father, but did not have clear rules for
renunciation of citizenship or the
naturalization of
aliens. Imperial Chinese subjects were traditionally severely restricted from traveling overseas and international travel was only sanctioned for official business. Disputes arising from nationality questions became more common as the
Qing dynasty was forced through a series of
unequal treaties to open up trade with Western empires and allow its subjects to migrate overseas. Women who married foreigners lost Chinese nationality if they took the nationality of their husbands. Nationality could be inherited perpetually from Chinese fathers, making it difficult to lose for men. These regulations were enacted in response to a 1907 statute passed in the
Netherlands that retroactively treated all Chinese born in the
Dutch East Indies as Dutch citizens.
Jus sanguinis was chosen to define Chinese nationality so that the Qing could counter foreign claims on
overseas Chinese populations and maintain the perpetual
allegiance of its subjects living abroad through paternal lineage. The 1909 law placed restrictions on Chinese subjects with
dual nationality within China. At the time, foreign powers exercised
extraterritoriality over their own nationals residing in China. Chinese subjects claiming another nationality by virtue of their birth in a
foreign concession became exempt from Qing taxation and legal jurisdiction within Chinese borders. A strict policy against automatic expatriation was adopted to prevent this; a Chinese individual's foreign nationality was not recognized by Qing authorities unless specifically approved.
Modern China Nationality law remained largely unchanged in the
Republican China. During this period,
Sun Yat-sen lectured against the idea of assimilating Europeans into the Chinese nation. After the
Communist Revolution, the new government abolished all republican-era legislation but did not immediately create laws to replace them.
Mainland China lacked formal nationality regulations The government unofficially applied the 1929 statute during this time to resolve nationality issues, and also made a mother's nationality normally transferable to her children outside of cases where the father is stateless. The
PRC does not recognize dual nationality and actively discouraged its occurrence in its treaties with
Indonesia,
Nepal, and
Mongolia in the 1950s. When the
National People's Congress adopted the current nationality law in 1980, a further stipulation was added that automatically revokes nationality from Chinese nationals who settle overseas and voluntarily acquire foreign citizenship.
Special administrative regions Hong Kong was a
British colony from 1842 until its
transfer to China in 1997. It initially consisted only of
Hong Kong Island and was expanded to include
Kowloon Peninsula and
Stonecutters Island in 1860. These areas were ceded in perpetuity to the United Kingdom by the Qing dynasty after the
Opium Wars. Britain
negotiated a further expansion of the colony to include the
New Territories in 1898, which were leased (rather than ceded) from China for a period of 99 years. Towards the end of this lease, the British and Chinese governments entered into negotiations over the future of Hong Kong and agreed on the
Sino-British Joint Declaration in 1984. The entire territory of Hong Kong would be transferred to China at the conclusion of the New Territories lease in 1997 and governed under Chinese sovereignty as a
special administrative region.
Macau was established as a trading post in 1557 permanently leased to the
Kingdom of Portugal by the
Ming dynasty. The territory was later fully ceded in the 1887
Sino-Portuguese Treaty of Peking, but
returned to China in 1999. Following the 1974
Carnation Revolution, Portugal formally relinquished Macau as an
overseas province in 1976 and acknowledged it as a "Chinese territory under Portuguese administration." After negotiations on Hong Kong's future had concluded, China and Portugal began deliberations on Macau in 1986 and agreed on the
Sino-Portuguese Joint Declaration in 1987. Macau would be transferred to China in 1999 and governed largely under the same terms as Hong Kong. Although most Hongkongers at the time were
British Dependent Territories citizens (BDTCs) and a substantial number of Macau residents held
Portuguese citizenship, China treats all ethnic Chinese born in these territories before and after the handovers as Chinese nationals. Hong Kong BDTCs who did not have strong ties to another
British Dependent Territory lost BDTC status on July 1, 1997. Former ethnic Chinese BDTCs could retain British nationality if they had voluntarily registered as
British Nationals (Overseas) while Macau residents with Portuguese citizenship were permitted to continue that status in all cases. However, Chinese authorities treat these individuals solely as Chinese nationals and bar them from receiving British or Portuguese
consular assistance while in Chinese territory. Given that a large number of Hongkongers and Macanese continue to hold dual nationality after the handover, the
Standing Committee of the National People's Congress issued two sets of "Explanations" of the nationality law as implemented in the special administrative regions so that Hong Kong or Macau residents who acquire a foreign nationality do not lose their Chinese nationality unless they file a declaration of change of nationality. Since 2021, the government of Hong Kong started refusing to allow consular protection to dual nationals, citing the policy that Hong Kong residents of Chinese descent, whether born in the city or on the mainland, are regarded as Chinese nationals and thus are ineligible.
Territory controlled by Taiwan The Republic of China (ROC) governed mainland China from 1912 to 1949. Near the end of the
Chinese Civil War, the Nationalist government was forced to
retreat to Taiwan by
Chinese Communist Party forces, and it subsequently established the
People's Republic of China (PRC) in 1949. Since the conclusion of the war, the ROC has controlled only the
Taiwan Area. Because both the PRC and ROC constitutionally claim areas under the other's control, the two governments treat each other's nationals as their own. == Acquisition and loss of nationality ==
