It is my guess that China, having let the fat kid with the crazy hair cut run amok for so long, is now afraid of North Korea and its limited nuclear capacity. The archaic saving face philosophy leaves China without any teeth in the issue other that to threaten others not to take action. Possibly what is needed is a third party, other than Japan, to take action with either the backing of the US, China or both.
