Moon’s comments came after Kim issued his harshest criticism yet of South Korea’s diplomatic role last week, accusing Seoul of acting like an “overstepping mediator” and demanding that it diverge from Washington to support the North’s position more strongly, AP reported.
Moon met Kim three times last year and also brokered nuclear talks between North Korea and the US.
In June, Trump and Kim opened up a face-to-face dialogue after months of trading military threats and pointed barbs.
The two leaders signed a vaguely worded document on denuclearization of the Korean Peninsula, but progress has since stalled as Washington and Pyongyang spar over the meaning of the document.
North Korea has taken few concrete steps to abandon its nuclear and ballistic missile programs.
But there are fears in Seoul that the hopeful developments of 2018 could be undone because of the mismatched demands between Washington and Pyongyang over sanctions relief and disarmament, which have derailed a high-stakes Trump-Kim meeting and prolonged a stalemate in negotiations.
Kim said that he is open to a third summit with Trump, but set the year's end as a deadline for Washington to offer mutually acceptable terms for an agreement to salvage the high-stakes nuclear diplomacy, the North's state-run media said Saturday.
"We of course place importance on resolving problems through dialogue and negotiations. But US-style dialogue of unilaterally pushing its demands doesn't fit us, and we have no interest in it," Kim said.
Kim blamed the collapse of his summit with Trump in February on what he described as unilateral demands by the United States, which he said raised questions over whether Washington has genuine willingness to improve relations.
Trump and Kim met again in Vietnam in February, but the summit collapsed over what the Americans saw as North Korean demands for sanctions relief in exchange for disarmament steps.
Pyongyang apparently has been trying to drive a wedge between Washington and Seoul by appealing to Moon’s enthusiasm for engagement.
“Whenever North Korea is ready, we hope that the South and North could sit down together and hold concrete and practical discussions on ways to achieve progress that goes beyond what was accomplished in the two summits between North Korea and the United States,” Moon said in a meeting with senior aides.
Moon’s office did not provide a timeline on when his fourth summit with Kim might take place.
