Looks like Kim just got everything he wanted and needs from China and Russia. So there is no need to give up anything.
He has skillfully run around the UN sanctions with Russia and China help, yes, big time, with ship to ship transfers, arms sales to Middle East, extensive cybercrime, Chinese land transport in. They are not hurting nearly as much as they were one or two years ago. Everything has been so relaxed and made full of holes as a result of detente with Seoul and Washington, which Seoul under that commie Pres Moon Jae In is fully responsible for kicking off early last year. Brilliant stroke by Pyongyang to have played it for awhile, or as far as they could. It was bound to unravel as it was not built upon anything substantive nor sincere. Just more of the same dishonesty and paranoia in Kims world.
