This poses an interesting question about ownership of space junk re-entering Earths atmosphere which will be an increasing problem in years to come.
One day this junk will either damage property or kill/ injure someone so what will happen then?

The real problem is that it may reach a critical point and render NEO almost unusable. Another problem where responsible international diplomacy is required to solve it ... so not much chance with the west still trying to rule the globe by fiat. [skeptoid.com]
China has been the least responsible regarding space junk returning to Earth. Very unlikely to drop in high population zones so they just don't care.
Not many care it seems. Everyone's putting satellites up now, getting crowded up there.
@puff NASA has criticized China for not sharing data on the descent of their debris [theguardian.com]
@barjoe NASA is a shadow of their former self. Can't even get a person to/ or retrieve from space now. I'm sure "5 eyes" assets are able to track space debris without Chinese input, not that they would do anything with the info unless it was heading for some military asset.
NB From a strategic point of view, I doubt NASA would share tracking info with China either as that will reveal your capabilities.
@barjoe It's why I strongly support the ideal that near space, any space should not be militarised. Trump's "Space Force" scared the shit out of me, recalling Ronnie Raygun's "Star Wars" days.
Have not seen any back peddling on that POTUS Trump initiative though so not all Trump was bad according to democrats (not what they say, what they do). Space Force is still a thing with a budget as far as I am aware.
@barjoe You are probably correct, but may be a case of China will share when it wants the US to know what it is capable of. Bit like Russia with their hypersonic missiles; That capability would have been Top Secret until it was decided that it would be more advantageous to let the opposition know your new capabilities.
