SEOUL, South Korea (AP) — South Korean President Moon Jae-in said Monday he's ready for a fourth summit with North Korean leader Kim Jong Un to help salvage faltering nuclear negotiations between the North and the United States.
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.
Moon met Kim three times last year and also brokered nuclear talks between North Korea and the U.S. following tensions created by the North's nuclear and missile tests and the exchange of war threats by Kim and President Donald Trump.
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.
It's difficult for Moon to make further progress on inter-Korean engagement without some level of sanctions relief, which Washington says won't come until unless Kim commits to verifiably relinquishing his nuclear facilities, weapons and missiles. Kim has shown no signs that he's willing to give away an arsenal he may see as his strongest guarantee of survival, and 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.
Moon met with Trump last week in Washington, where they agreed on the importance of nuclear talks with North Korea but did not announce a specific plan to get the stalemated negotiations back on track.
Moon spent the past year making aggressive efforts to stabilize South Korea's hard-won detente with North Korea and improve bilateral relations. He also lobbied hard to set up the first summit between Kim and Trump last June, when they agreed to a vague statement about a nuclear-free Korean Peninsula without describing how or when it would occur.
Trump and Kim met again in Vietnam in February, but the summit collapsed over what the Americans saw as excessive North Korean demands for sanctions relief in exchange for limited disarmament steps.
Moon has said it is Seoul's "outmost priority" to prevent nuclear negotiations between the U.S. and North Korea from derailing, and there is speculation that he will soon announce a plan to send a special envoy to Pyongyang, North Korea's capital, in an effort to rescue the talks.
North Korea in recent weeks has been registering displeasure with Seoul, withdrawing its entire staff from a front-line liaison office with South Korea before sending some of them back, and refusing to show up for a previously planned joint search for war remains at the countries' border.
The breakdown of the Trump-Kim meeting in February raised doubts about Moon's claim that Kim could be persuaded to deal away his nuclear weapons for economic and security benefits and also about Seoul's role as a diplomatic catalyst, which became less crucial once Washington and Pyongyang established direct talks.
North Korea had been urging the South to break away from Washington and proceed with inter-Korean economic projects that are currently held back by sanctions.
In their third summit last September, Moon and Kim agreed to reconnect the Koreas' railways and roads, normalize operations at a jointly run factory park in the North Korean border town of Kaesong and restart South Korean tours to the North's scenic Diamond Mountain resort, voicing optimism that international sanctions could end and allow such projects.
But Moon's call for partial sanctions relief to create space for the inter-Korean projects and induce nuclear disarmament steps by North Korea has led to a disagreement with Washington, which sees economic pressure as its main leverage with Pyongyang.
In a speech delivered to North Korea's rubber-stamp parliament on Friday, Kim said he is open to a third summit with Trump but set an end-of-year deadline for Washington to offer mutually acceptable terms for an agreement.
Kim blamed the collapse of the second summit with Trump on what he described as Washington's unilateral demands. He said the North's economy would prevail despite the heavy U.S.-led sanctions imposed over its nuclear weapons program and that he wouldn't "obsess over summitry with the United States out of thirst for sanctions relief."
On South Korea, Kim said Seoul "should not act as an 'overstepping mediator' or a 'facilitator' and should rather get its mind straight as a member of the (Korean) nation and boldly speak up for the interest of the nation."
Kim also accused South Korea of deferring to the "anachronistic arrogance and hostile policy" of the United States and berated the ongoing military exercises between the allies. Although they described the exercises as defensive in nature, the United States and South Korea have downsized the drills to create a space for diplomacy with North Korea, which sees them as invasion rehearsals.
Moon did not directly address Kim's criticism, but said he has "high regard" for what he saw as Kim's strong commitment to diplomacy.
Kim's speech came after North Korea's Supreme People's Assembly made a slew of personnel changes that bolstered Kim's diplomatic lineup. Experts said this could be a sign of his desire to keep recent months of up-and-down nuclear diplomacy alive rather than returning to the threats and weapons tests that characterized 2017, when many feared possible war on the Korean Peninsula.
