oh sweet Jeebus! GEO refers to ...
(a) an altitude at which Geosynchrony can be achieved with low additional energy usage i.e. thrusters, AND
(b) the orbits of bodies that have achieved an orbital speed equal to the rotation of the planet regardless of whether they use energy to stay there or not
Now that might sound like it is standing still but actually it means that it is belting along at a massive lick and could clobber anything that crosses its path going in, going out or traversing at any angle to its orbital sphere.
Loads of stuff comes in (literally tons a day) from space and includes things too small for the naked eye to see and things even bigger than Paris's inflatable head.
A fair amount traverses those orbits going up too, things on their way to Mars for example, and often shedding little bits ranging from paint flecks to tools to great big panels as they go.
On top of that, if a geostationary satellite sheds any bits, there is no guarantee that those bits will continue to share the same orbit, and can't start accelerating ever so slowly as they wind downwards back to the planet at ever increasing speeds for ever so long because of drag, collisions, or separation vectors. After many moons of a very modest acceleration some pretty amusing and entertaining velocities can be attained - in the order of many thousands of meters per second.
At which point a paint fleck can punch a rather satisfying hole in a duraluminium plate.
As far as China is concerned, well their response to the weaponization of space and GPS-guided munitions was to hint that (a) they could shoot stuff down if they liked, and (b) if they wanted to they could heave a busload of little ball-bearings up there and put a stop to people guiding things or threatening to launch stuff from up there.
Perhaps one should pay attention to this simple practical demonstration that if you bring your guns and grenades into the pool, they shall crap in it and laugh at you.
