On June 12, 2020, the two-year anniversary of the Singapore summit, the North Korean Minister of Foreign Affairs released a press statement that the Trump administration efforts in the past two years were for political achievements without returns for North Korea and "Nothing is more hypocritical than an empty promise." North Korea subsequently cut communications with South Korea, demolished the four-story joint-liaison office building it shared with South Korea on June 17, and ceased efforts for diplomatic relations with the United States.
