Official Statements and Evidence
"The aviation division follows the One-China policy, only mainland China is allowed," Defense Minister Khawaja Asif told Bloomberg, adding, "We have permitted only Chinese airlines to fly over Pakistan."
According to Bloomberg, no country had previously imposed a blanket overflight ban on Taiwanese commercial airlines. In April, Seychelles, Mauritius and Madagascar withdrew overflight clearances for Taiwanese President Lai Ching-te's aircraft, forcing him to postpone a visit to Eswatini. Lai eventually made the trip in May. Taiwanese airlines had also largely avoided Russian airspace after the escalation of the Ukraine conflict in 2022, although neither Moscow nor Taipei formally prohibited them from using it.
