Sorry, Beijing – you don't own the airspace (thehill.com)

> Taiwanese President Lai Ching-te was forced to cancel a trip to Eswatini (formerly Swaziland), the island’s only diplomatic ally in Africa, after three countries along the flightpath — Seychelles, Mauritius, and Madagascar — rescinded permission for Lai’s presidential aircraft to fly over their countries. Lai was scheduled to attend celebrations commemorating the 58th anniversary of diplomatic relations with Eswatini.

So... The PRC does effectively own the airspace.

Before I clicked on this I thought it was going to be about Beijing banning drones.
