Kim visits Xi

North Korean leader Kim Jong-un has visited China again.

Xi told Kim, among other things, that he welcomes the meeting between the leaders of North Korea and the US. That conversation is scheduled for the end of this month or the beginning of June.

Kim's trip by plane follows a more remarkable visit in March. He, like his father Kim Jong-il, traveled to China in a special armored train. It was his first trip to China since his arrival in 2011.
