War in Korea would be a political and economic headache the Chinese government wouldn't want to have. They would topple Kim and install a new mini-dictator first. He's only there in the first place because China allows it.

This is the classic case of doing nothing to avoid headache now, kicking a can down the road, whether it turns into a bigger problem or not.

That would give Chia Head a wrong message, making him push envelope ever further. Because of their lack of action, Chia Head is turning into a bigger and bigger headache. He is incrementally maneuvering himself into a position of greater leverage, even against China. Of course, Chia Head is dying and Chia hopes that this headache would end soon and they would have a free hand on shaping N. Korea's future heavily in their favor. They are saying to themselves, "OK. Wait a little longer. Another month or another year, and this will go away. Let's be a little more patient." However, Chia Head create real problem even before he dies. It also gives time to Chia Head to put measures in place for Chinese encroachment, creating a situation they cannot control, making their intervention extremely costly even though China can prevail in the end.
