The border tensin is mounting on India's border with China. Will that conflict divide China's military in the event the USA has a war with NK. Could such a divide of Chinese forces limit their obstruction to the battle with Un? Could it be what Trump needs?
not too much china has different army division for different region, and I doubt china will involve in NK vs US, the troop near NK is mainly to stop the millions refugees if war break out.
China's land power is maaaaasssssivveeee, to turn them back without nuclear weapons would be a feat in itself. They could handle the small pass in India, not a full invasion since India is a close second there
