Though probably unrelated, multiple sources indicating further buildup of chineese forces along the border with NK. Most likely to handle refugee.
NK military has been given a stand down to scavenge for food across the country side.
It’s my understanding whenever there are oil sanctions, as have been in play now, China always increases tents and military on the border to control the N.Koreans spilling over from the cold.
Interesting also is solar energy has become popular as a main means of heating or backup in N.Korea for those who can afford doing so.
