How many nationalities can there be in China?

Only one China nationality is allowed, and dual citizenship of China citizens is not recognized. People's Republic of China (PRC) nationality is applicable to people from Chinese mainland, Hongkong and Macau under the jurisdiction of People's Republic of China (PRC) and People's Republic of China (PRC). The Nationality Law of the People's Republic of China adopts the principle of combining bloodline with birthplace on the issue of birth nationality. China citizens are not recognized as having dual citizenship.

According to the Nationality Law of the People's Republic of China, a China citizen who has settled in a foreign country will automatically lose his China nationality if he voluntarily joins or acquires a foreign nationality. A child born in China with a China citizen is of China nationality, and the foreign nationality of the child is not recognized in principle unless a China citizen has settled in the host country, including one of the husband and wife is a citizen of the country where the birth right is located or a citizen of a third country has the nationality of the host country.

The nationality law of Taiwan Province Province is based on "individualism (consanguinity)" and "territorialism (nativism)". "Except for senior civil servants and public officials, China people are allowed to have dual nationality." In other words, unless approved by the Ministry of the Interior, China residents in Taiwan Province Province who become foreign citizens will not lose their China citizenship.

For this reason, it often happens that citizens of Taiwan Province province in China hold passports from China and Taiwan Province provinces, as well as passports from Britain, the United States, Australia, New Zealand and other foreign countries. "However, foreigners who join China nationality in Taiwan Province Province must first give up their original nationality", unless it can be proved that they cannot obtain the certificate of loss of their original nationality due to reasons not attributable to the parties concerned, which is verified by diplomatic authorities.
