SEOUL, June 7 (Reuters) – Kim Yo Jong, the sister of North Korean leader Kim Jong ‌Un, said North Korea will never back ‌down on its status as a nuclear-armed state, warning that ​it will not tolerate any threats, state media agency KCNA said on Thursday.

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.

Kim ​Yo Jong also called ‌U.S. claims that Xi and U.S. President Donald Trump confirmed a goal to denuclearize during a May summit “false.”

“We have the most accurate information” on whether the claims are true or not, she said, without ‌elaborating.

Early this week, North Korea ​unveiled a new nuclear material ​production factory where ​Kim Jong Un called for an “exponential” ‌expansion of the country’s atomic ​arsenal.

Analysts said ​the new uranium-enrichment site appeared aimed at reinforcing North Korea’s negotiating position ahead of the Xi-Kim ​summit while ‌justifying an acceleration of its nuclear build-up.
