Yes, they can but if PRC do want to "invade" DPRK, they don't need to do it by military force. PRC can just turn off the oil and food supply in Winter and Kim's regime will be on his knees. This saves PRC the bad publicity of "invading" and "ally". Don't you think so?
PRC can just turn off the oil and food supply in Winter and Kim's regime will be on his knees. As I recall they did shut down the oil line to Kim for a short period to remind him who was calling the shots.
What I don't understand, is why the PRC doesn't shut it down and bring him to his knees. It seems so simple to me; but then I'm sure not an expert, far from it.
