Q25: Why does the IAU use the terms "China Nanjing" and "China Taipei" for national membership?
A: The "China-Nanjing" and "China-Taipei" denominations used in the IAU refer to the seats of the respective astronomical societies. Astronomers (including amateurs) in both geographical areas follow the official agreement on these denominations, which was signed by both parties and approved by the IAU General Assembly in 1982.
