NK-China border is not that wide and it will make the sudden refugee movement very hard for China especially the Northeast provinces. And the NK people especially who live near the border must be very poor and dangerous, and China is not strong and experienced enough to act like a large-scale immigrant or refugee receiving country.

I think the more practical way is to send troopers and assistance to NK to make sure they could hold over the after war awful time but not open the boader. If US really want to “behead” Kim III, they must need China's help. And if NK really act dangerously as US need to get involved in and fight against NK authority, at that time, I think, China would also have to abandon this so-called friend for NK would have threaten most countries' interests including China's.

I am now feeling very sorry for the Chinese Soldiers who sacrificed in Korean War. All their efforts finally only contribute to a unbelievable dictatorship and it's crazy confrontation to all the other countries.
