Chung Eui-yong, chief of the presidential National Security Office, made the remarks upon arriving at Incheon International Airport, west of Seoul, after his visit to Washington to meet his U.S. counterpart, John Bolton.

„We had in-depth discussions on ways to make the summit between the U.S. and North Korea successful,“ Chung said. „To that end, the South Korean and U.S. presidents are planning to have close consultations in Washington in mid-May.“
