China does not recognize the advantages and disadvantages of dual nationality, Zhihu.

Advantages: allowing dual nationality is conducive to introducing a large number of overseas Chinese talents, technology, funds and management experience, enhancing national cohesion and having dual nationality. For many China people living abroad, they can enjoy all the rights of citizens in their country of residence and keep their status as "China people", which is a kind of psychological comfort for China people who advocate returning to their roots. The most direct convenience brought by dual nationality to foreign Chinese is that there is no need to apply for a visa when returning to China.

Disadvantages are: dual nationality will allow some bad elements to take advantage of the law, and after breaking the law, some criminals may get away with it or get a lighter punishment; Different trial procedures will also give criminals an opportunity, which is difficult to punish. In addition, if China citizens are recognized as having dual nationality, it will lead to conflicts between China and relevant countries in exercising jurisdiction and protection rights over these dual nationals. Some scholars also pointed out that people with dual nationality can enjoy various legal preferential conditions than people with single nationality, which will lead to the inequality of citizens in competition.

Article 3 of the Nationality Law of the People's Republic of China People's Republic of China (PRC) does not recognize that China citizens have dual nationality.
