Territorial changes of the People's Republic of China

The territory of the People's Republic of China (PRC) has frequently been revised since its formation on 1 October 1949.

Until 1986, the total territory (or under control) of the PRC was 10.45 million km², including:

• Continental mainland: ~9.60 million km²
• Islands and reefs: ~75,400 km²
• Coastal beaches and shoaly lands: ~12,700 km²
• Inner sea (mainly Bohai Sea): ~693,000 km²
• Territorial (sea only) waters: ~220,000 km²

During the 1990s and 2000s, the official size and value of China's territory are rarely officially declared or published.

The Republic of China (ROC) government on Taiwan does not recognize the PRC's territorial changes to the 1947 ROC constitution (although amended in 1991 to include the ROC's free area).
