North Korean supreme leader Kim Jong Un announced Friday that he no longer wants to test nuclear weapons and ballistic missiles, reported South Korea’s official Yonhap News Agency. The statement would mark a major concession as the young leader prepares for his country’s first direct meeting with a sitting U.S. president, reportedly set to take place late next month or in early June. The announcement came via state media, which said a total freeze for nuclear tests would come into effect immediately local time.
