The 4,500-kilometre rail journey from Pyongyang to Hanoi says much about North Korea and its leader Kim Jong-un. A flight to meetings in Vietnam's capital with U.S. President Donald Trump on Wednesday and Thursday to address North Korea's nuclear weapons program would have been easier of course. Kim waves upon arriving in Vietnam on Tuesday for a summit this week to discuss North Korea's nuclear weapons program. On Sunday, Trump said he's "not in a rush" for an agreement with Kim that North Korea would get rid of its nuclear weapons. But there is growing evidence that sanctions enforcement has already eased, especially by China, North Korea's biggest trading partner by far.
