Tow it back home?
Call me stupid, but what prevents the UN (or whoever oversees international space treaties) demanding that China either sends up another spacecraft (or contracts another space agency, or, hello, SpaceX, to do so) to get alongside the space station, grab ahold of it, and then steer both craft into a planned safe de-orbit path?
I realise that there would probably be some hard calculations involved, but we have managed it before whenever spacecraft rendezvous and dock, and we did manage to get Apollo 13 safely back home after all!
