I won't speculate. But we can interpret what is already there. China has mobilized a great deal of troops at the NK border. This means China takes the threat from the US against Kim Jong seriously, and, it also means that China will move in to occupy NK to keep the US from establishing a stronghold next door.

Someone important in China recently said that if the US attacks NK, China will attack SK. Check for the validity of that claim. Naturally, if China doesn't want the US in NK, they really don't want them in SK either.

Yes, the recent US attacks in Syria and Afghanistan were meant as a message to Kim Jong, intentionally or not. Everyone here at the gangsterbb who studies mafia history can appreciate the impression made by first attacking one of Syria's airstrips with 80 million worth of tomahawk missiles, and then immediately sitting down to have dinner with the president of China right afterward, which is exactly what Trump did.
