SEOUL, South Korea—North Korean leader Kim Jong Un threatened to expand his nuclear arsenal as he disclosed a list of high-tech weapons systems under development, saying the fate of relations with the United States depends on whether it abandons its hostile policy, state media reported Saturday.
Kim’s comments during a key meeting of the ruling party this week were seen as applying pressure on the incoming administration of President-elect Joe Biden, who has called Kim a “thug” and has criticized his summits with President Donald Trump.
