North Korea indicated it may go back on certain concessions made to the U.S. after President Biden hit the hermit kingdom with new sanctions.
The isolated nation in recent weeks stepped up its weapons tests, including the test of supposed hypersonic weapons such as glide vehicles. The Biden administration hit five North Korean officials with sanctions in relation to the tests.
The sixth meeting of the Political Bureau of the Central Committee convened this week, with party General Secretary Kim Jong Un in attendance. The Politburo discussed a number of "confidence-building measures," one of which may be to backtrack on a self-imposed moratorium on testing nuclear weapons and intercontinental ballistic missiles in response to the sanctions.

"The DPRK's latest missile launches are further evidence that it continues to advance prohibited programs despite the international community's calls for diplomacy and denuclearization," said Treasury's chief of terrorism and financial intelligence, Brian Nelson.
North Korea previously agreed to a number of concessions during the Trump administration, including a statement on a nuclear-free Korean Peninsula without describing when and how that would occur.
Kim unilaterally suspended nuclear and intercontinental ballistic missile tests during discussions with Washington and Seoul, but continued a series of short-range missile tests during that time.
