Which country does the land ownership of the consulate belong to?

The ownership of the land belongs to the country, and the consulate is in another country, occupying the territory of another country. Of course, ownership belongs to the local government.

It means that the land of country A's embassy in China still belongs to country C, and only when the building is used as a country A's embassy or consulate will it be protected by the convention and enjoy diplomatic immunity. There are also local consulates that only rent a certain floor of a building, and of course only have diplomatic immunity on that floor.

Personnel from country C are not allowed to enter the internal area of the embassy or consulate at will, and their freedom of communication should be guaranteed; Diplomatic bags cannot be opened or detained.

Simply put, country A only has the right to use it, but when it is used as a diplomatic building, it has great authority. Although country C has property rights, it cannot enter at will. Once country A withdraws and the building is taken back, country C has the final say on this place.

International law does not say that the embassy or consulate is the territory of the sending country, nor does it say that a country's aircraft is an extension of its territory.

Extended data:

According to the Vienna Convention on Consular Relations, consulates are divided into consulates-general, consulates-general, vice-consulates and consular offices, which are responsible for the management of local nationals and other consular affairs. When two countries break off diplomatic relations, they will definitely cancel their embassies, but not necessarily their consulates.

The embassy represents the interests of the whole country and is fully responsible for bilateral relations. The curator is an ambassador, appointed by the head of state and performing his duties as a representative of the head of state. The primary duty of the embassy is to represent the sending country and promote the political relations between the two countries.
