A top North Korean official headed to NY on Wednesday for talks aimed at salvaging a summit between Kim Jong Un and President Donald Trump on the future of Kim's nuclear program, in the North's highest-level mission to the United States in 18 years.
On the nuclear question, the analysis suggests that a more realistic immediate objective would be convincing Kim to walk back recent progress on the country's nuclear weapons program, the officials said.
A team of US officials led by former USA nuclear negotiator Sung Kim began talks with North Korean officials at the Korean border village of Panmunjom on Sunday to set the agenda for the summit.
He also accompanied Kim Jong Un on both of his recent trips to China to meet President Xi Jinping and held talks with Secretary of State Mike Pompeo when he travelled to Pyongyang.
Kim Yong Chol is to meet with U.S. Secretary of State Mike Pompeo.
North Korea's flurry of diplomatic activity following a torrid run in nuclear weapons and missile tests in 2017 suggests that Kim Jong Un is eager for sanctions relief to build his economy and the worldwide legitimacy the summit with Trump would provide.
They met inside the Demilitarized Zone on the inter-Korean border, and "plan to have additional meetings this week", Sanders said.
A North Korean delegation led by another of Kim Jong Un's trusted aides, Kim Chang Son, flew to Singapore on Monday night for talks with US officials to discuss logistical issues for the summit.
United States negotiators, headed by Washington's current ambassador to the Philippines Sung Kim, met with North Korean counterparts in the truce village of Panmunjom that divides the two Koreas on Sunday.
But within 24 hours he reversed course, saying it could still go ahead after productive talks were held with North Korean officials.

These attacks came after months of using Palestinian human shields as cover for other attacks on Israel. Prime Minister Benjamin Netanyahu pledged a forceful response to the barrage of mortar shells fired.
Since then, North Korea has rejected US demands for it to unilaterally abandon its nuclear program, which experts say could threaten the United States.
Analysts believe the United States is trying to determine whether North Korea is willing to agree to sufficient steps toward getting rid of its nuclear weapons to allow a summit to take place.
During his tenure as a senior intelligence official, Kim was accused by South Korea of masterminding deadly attacks on a South Korean navy ship and an island in 2010.
South Korean media also reported that a North Korean delegation arrived in Singapore on Monday night, where other US officials, led by White House deputy chief of staff Joe Hagin, are preparing for the summit.
Since that short-lived crisis, diplomats in both countries have conducted an intense flurry of negotiations, culminating on Thursday when Pompeo sat down in NY with Kim's number two, Kim Yong Chol.
In an odd twist, a list of potential concessions by North Korea in the Central Intelligence Agency analysis included the possibility that Kim Jong Un may consider offering to open a Western hamburger franchise in Pyongyang as a show of goodwill, according to three national security officials.
"But, as the president has said", she added, "if it doesn't happen June 12 it could happen thereafter". That was a shift from last week, when Trump announced in an open letter to Kim Jong Un that he had chose to "terminate" the summit following a provocative statement from the North.
In Kim Jong Un and Moon's first meeting on April 27, they agreed to seek the "complete denuclearisation" of the Korean peninsula but did not define what that meant or how that would proceed.
Since the 1970s, the United States and South Korea have been holding a major summertime exercise called Ulchi Freedom Guardian that involves tens of thousands of troops. Moon has insisted he 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.
