It is widely believed that Kim Jong-un is in Beijing Tuesday, called there by a Chinese government that wants to know what he is up to. At the very least, it is said, China wants in on the act if Donald Trump is really going to meet the little dictator from Pyongyang. In the US, the state department said it had no information but added tartly that it seems the free world is in a much better place with North Korea than it was a year ago. That’s because of the pressure being brought not just by the US and its allies, but China too, for Kim to renounce nuclear weapons.
