Interestingly enough, the extent of a country's sovereignty in (air)space is legally quite unclear. It's pretty well established that countries can regulate planes and such flying at an altitude of ~10 km, and the Outer Space Treaty bans claims on celestrial bodies, but everything in between (including Starlink's satellites in LEO, some 2,000 km from the Earth's surface) is in a grey zone. Legal issues aside, they're also quite literally beyond the reach of all but a small handful of spacefaring nations, and even a nation like China that has the technical capability would not resort to actively shooting them down unless other avenues were exhausted.
