Should I give up my nationality when applying for German nationality, because China does not support dual nationality?

Nationality refers to a person's legal qualification as a national or citizen of a certain country, indicating a fixed legal connection between a person and a specific country, and is the legal consultant basis for the country to exercise personal jurisdiction and diplomatic protection.

Dual nationality means that a person acquires the nationality of country A through procedures and acquires the nationality of that country again in country B. In public international law, nationality is the basis for a natural person to have a loyal obligation to a country and for the country of nationality to exercise diplomatic protection. A person with multiple nationalities may have loyal obligations to many countries, which often brings him a lot of trouble, especially in wartime. If there is a war between his two countries of nationality, no matter which side he chooses to be loyal to, it will be regarded as treason by the other side. Stateless people do not have these loyalty obligations, but when their rights are damaged in a country, they will not receive diplomatic protection from any country.

Each country determines which natural persons have their own nationality according to its own nationality law. There seems to be no conflict. But in fact, due to the different principles of granting nationality in different countries, some people may have multiple nationalities, while others may have no nationality, thus causing nationality conflicts. In international justice, the situation that a person has two or more nationalities at the same time is called active nationality conflict; A person who has no nationality is called a negative conflict of nationality. If it is necessary to apply the domestic law of the parties in a certain legal relationship, then in the case of active conflict, it is necessary to determine which nationality of the parties shall prevail; In the case of passive conflict, because the parties have no nationality, it is necessary to determine what law should be applied.

The conflict between positive and negative nationality occurs because different countries have different regulations on the acquisition, loss and restoration of nationality.
