Discussions between the U.S. and North Korea "have moved more quickly than expected," the White House said in a statement.
President Donald Trump is set to meet North Korean leader Kim Jong Un in Singapore June 12 and return to the U.S. later that day.
The meeting, at 9 a.m. local time Tuesday, will be a one-on-one meeting with translators present, an expanded bilateral meeting and a working lunch, according to the White House.
Secretary of State Mike Pompeo, Chief of Staff John Kelly and National Security Advisor John Bolton will be among the attendees of the bilateral meeting.
