Interesting development! Kim can embarrass the Chinese by heeding their warning, make himself appear to be their puppet, lose a little face in order to make them lose face.
Of course if he doesn't take heed, they would lose more face and---he could lose more than face.
This is embarrassing to the US. They flip us the bird and China goes over once and he cowers like a dog. This makes China look strong and we look like crap.
