I think Chinese regime is retaliating against outsiders pressuring China to honor human rights of N. Korean refugees. They don't take it kindly. They may also feel the need to rein on N. Korea to get out of the boundary they set. Seems like China is propositioning a deal: we clamp down refugees and you stop your belligerence. It may not work and China probably knows it, but it may not care, either. China just wants to get rid of source of international outcry. If it can muzzle N. Korea as another side-benefit, it is great, but not a main objective.

Yes, they have a lot of prestige, and that might cause problems, but I think that they really are fed up with the Norks.
