An American delegation met with North Korean officials in the Demilitarized Zone on Sunday as planning seemed to move ahead for the on-off-perhaps-on-again summit between President Donald Trump and North Korean leader Kim Jong Un.
South Korea’s president, Moon Jae-in, meanwhile, gave details about his surprise meeting Saturday with Kim in the Panmunjom truce village, saying Kim had committed to sitting down with Trump and to a “complete denuclearization of the Korean Peninsula.”

U.S. Secretary of State Mike Pompeo tapped veteran American diplomat Sung Kim to handle pre-summit negotiations. On a separate but complementary track is the CIA team Pompeo set up last year when he headed the spy agency. And on a third track is a White House logistical group sent to Singapore this weekend to prepare in case the summit takes place. It was led by Joe Hagin, White House deputy chief of staff for operations.
Kim, the U.S. ambassador to the Philippines, also served as ambassador to South Korea and was part of the U.S. negotiating team that last held substantive denuclearization talks with North Korea during the George W. Bush administration in 2005.
The developments, after last week’s whirlwind of uncertainty, appeared to flesh out Trump’s assertion that the June 12 summit in Singapore that he canceled Thursday could take place as first scheduled. Trump told reporters Saturday that there was “a lot of goodwill,” that the original plan was still being considered and that “that hasn’t changed.”
“We continue to prepare for a meeting,” State Department spokeswoman Heather Nauert said in Washington as she confirmed that an American delegation was “in ongoing talks with North Korean officials” in Panmunjom in the DMZ, which separates the two Koreas.
The Korean leaders’ second summit in a month saw bear hugs and broad smiles. But their quickly arranged meeting Saturday appeared to highlight a sense of urgency on both sides of the world’s most heavily armed border.
The talks, which Moon said Kim Jong Un requested, capped a whirlwind 24 hours of diplomatic back and forth. They allowed Moon to push for a U.S.-North Korean summit that he sees as the best way to ease animosity that had some fearing a war last year.
Kim may see a meeting with Trump as necessary to easing pressure from crushing sanctions and to winning security assurances in a region surrounded by enemies.

Moon told reporters that Kim “again made clear his commitment to a complete denuclearization of the Korean Peninsula.” Moon added that Kim said he’s willing to cooperate to end confrontation and work toward peace for the sake of the successful summit with Trump.
Moon said he told Kim that Trump has a “firm resolve” to end hostile relations with North Korea and initiate economic cooperation if Kim implements “complete denuclearization.”
“What Kim is unclear about is that he has concerns about whether his country can surely trust the United States over its promise to end hostile relations (with North Korea) and provide a security guarantee if they do denuclearization,” Moon said.
“During the South Korea-U.S. summit, President Trump said the U.S. is willing to clearly put an end to hostile relations (between the U.S. and North Korea) and help (the North) achieve economic prosperity if North Korea conducts denuclearization,” he said.
Kim, in a dispatch issued by the North’s state-run news service earlier Sunday, “expressed his fixed will on the historic (North Korea)-U.S. summit talks.” During Saturday’s inter-Korean summit, the Korean leaders agreed to “positively cooperate with each other as ever to improve (North Korea)-U.S. relations and establish (a) mechanism for permanent and durable peace.”

They agreed to have their top officials meet again June 1. Moon said military generals and Red Cross officials from the Koreas will also meet separately to discuss how to ease military tensions and resume reunions of families separated by the 1950-53 Korean War.
Saturday’s Korean summit came hours after South Korea expressed relief over revived talks for a Trump-Kim meeting.
Despite repeated references to “denuclearization of the Korean Peninsula” by the North, it remains unclear whether Kim will ever agree to fully abandon his nuclear arsenal.
The North has previously used the term to demand the United States pull out its 28,500 troops in South Korea and withdraw its so-called nuclear umbrella security commitment to South Korea and Japan. The North hasn’t openly repeated those same demands after Kim’s sudden outreach to Seoul and Washington.
Moon has insisted Kim can be persuaded to abandon his nuclear facilities, materials and bombs in a verifiable and irreversible way in exchange for credible security and economic guarantees. Moon said Sunday that the North’s disarmament could still be a difficult process even if Pyongyang, Washington and Seoul don’t differ over what “complete denuclearization” of the peninsula means.
WATCH: Trump cancels North Korea summit in letter to Kim
Before he canceled the summit, Trump did not rule out an incremental approach that would provide incentives along the way to the North.
Following an unusually provocative 2017 in which Kim’s engineers tested a purported thermonuclear warhead and three long-range missiles theoretically capable of striking mainland U.S. cities, the North Korean leader has engaged in a flurry of diplomatic activity in recent months. He has had the summits with Moon and Chinese leader Xi Jinping, as well as two meetings with Pompeo.
