South Korean president Moon Jae-in also will meet with the North Korean leader soon. Mr. Chung is part of a South Korean delegation visiting Washington following the talks this week in Pyongyang.
Mr. Chung said that the North Korean leader is “committed to denuclearization,” and that he pledged to refrain from any further nuclear weapons or ballistic missile tests. He said Mr. Kim also has accepted that the U.S. and South Korea will go on with “routine” military exercises scheduled for next month.
“I explained to President Trump that his leadership and his maximum pressure policy, together with international solidarity, brought us to this juncture,” Mr. Chung said, adding that he expressed Mr. Moon’s “personal gratitude” for Mr. Trump’s leadership on confronting Pyongyang.
White House National Security Adviser H.R. McMaster is to brief U.N. Security Council envoys on North Korea on Monday, Reuters reported.
Earlier Thursday, Secretary of State Rex Tillerson played down hopes for a breakthrough on North Korea’s nuclear program, saying the U.S. is a “long way” from negotiations after the country’s leader offered to give up his weapons in exchange for security guarantees.
