China's recent air force maneuvers around Taiwan have caused consternation and confusion. However, there are critical distinctions to be made between rules on entering different kinds of airspace.
The US has expressed its concern over the appearance of Chinese military jets in Taiwan's air defense zone. Beijing has now flown planes through the zone for three days in a row.
It is the second day in a row that China sent a record number of warplanes into the island's Air Defense Identification Zone, Taiwanese officials said.
Defense officials have accused Beijing of "damaging regional peace" after China flew an unprecedented 38 military aircraft into the Taiwanese air defense zone, including nuclear-capable bombers.
