Chinese leader Xi Jinping will travel to North Korea next week in first visit in years

The announcement came a day after North Korea unveiled a new facility to produce nuclear bomb fuels. During a visit to the plant, Mr. Kim announced plans to bolster the country’s nuclear forces “at an exponential rate.”

Experts say the plant’s disclosure implies that Kim is eager to cement his country’s status as a nuclear weapons state ahead of Xi’s visit to Pyongyang.
