Days after North Korea sparked outcry in Washington for test-firing its first ballistic missiles of the year, a top White House spokesperson told reporters that U.S. President Joe Biden may not be open to a sit-down with North Korean leader Kim Jong Un.

On Monday, reporters asked U.S. Press Secretary Jen Psaki whether Biden would meet with Kim, referencing the U.S. president’s comment earlier this month that he was “prepared for some form of diplomacy” with North Korea. Biden made the mark on March 24, hours after North Korea launched two ballistic missiles towards the East Sea in violation of multiple U.N. Security Council resolutions.
