On the same day his Hanoi meeting with Kim fell apart, Trump called Moon to ask for his help. “While expressing disappointment over the failure to reach an agreement in the summit, President Trump reaffirmed his determination to resolve the issue through dialogue with North Korea in the future,” Cheong Wa Dae said of the telephone conversation earlier. “In addition, (Trump) asked President Moon to actively perform the role of a mediator that may entail talking with Chairman Kim and letting him know the outcome of his dialogue.” Moon and Trump have apparently decided they should talk first. On top of the agenda for their talks will likely be how much they will give to North Korea.

Trump has said his second summit with Kim fell through largely because the North wanted international sanctions lifted “in their entirety, but we couldn’t do that.” He has also said the sanctions should and will be maintained until Pyongyang fully denuclearizes. Moon, on the other hand, has stressed the need for some carrots in addition to sticks. “I believe North Korea needs to take practical denuclearization steps more boldly if it wishes to resolve the issue of international sanctions because the issue of international sanctions depends on the speed of North Korea’s denuclearization process,” Moon said in his news conference for the new year held Jan. 10. “I believe corresponding measures too must be considered to further promote North Korea’s denuclearization process,” he said.

Following his recent trip to the U.S., the NSO deputy director, Kim, said Seoul and Washington were on the same page regarding the “end state” of North Korea’s denuclearization and how to get there. A ranking Cheong Wa Dae official reiterated that the countries completely agreed on what a nuclear-free North Korea should look like and how to reach such a state, but apparently only at the macro level. “What is important is that (Seoul and Washington) agree on the end state of complete denuclearization, the roadmap and that their top-down approach must be maintained,” the official told reporters, referring to the recent summit meetings with the North Korean leader. Whether the countries should offer phased rewards to the North will be discussed at the upcoming summit, the official said when asked.

Moon’s upcoming talks with Trump will inevitably be followed by dialogue with the North Korean leader. No schedule has been set for a fourth Moon-Kim summit, but the North Korean leader has promised to visit South Korea to reciprocate the South Korean leader’s trip to Pyongyang last year. Moon’s chief security adviser Chung Eui-yong has also hinted at the possibility of Moon sending a special envoy to North Korea.
