North Korean leader Kim Jong Un stuck to a familiar playbook at a party congress, vowing to develop more advanced nuclear weapons and missiles and lambasting the United States as its “biggest enemy,” state-run media said Saturday, less than two weeks before U.S. President-elect Joe Biden takes office.

Kim delivered the challenge to Biden at the key meeting a day earlier, saying that Washington’s “hostile policy” toward Pyongyang would continue regardless of who occupies the White House.

"Our foreign political activities should be focused and redirected on suppressing and subduing the U.S., our biggest enemy and main obstacle” to the North’s development, the official Korean Central News Agency quoted Kim as saying during a marathon nine-hour report to the rare session of party congress.
