Kim Yo-jong, the sister of North Korean leader Kim Jong-un, says North Korea will never back down on its status as a nuclear-armed state, warning that it will not tolerate any threats.
Chinese President Xi Jinping is set to visit North Korea on Monday for the first time in nearly seven years as Beijing looks to reinforce ties with Pyongyang, China's only formal treaty ally.
Xi will meet Kim Jong-un and exchange views on bilateral relations and issues of common concern, China's foreign ministry said.
