Senior North Korean official Kim Yong Chol met with US Secretary of State Mike Pompeo in New York, Wednesday, ahead of a potential summit in Singapore between the leaders of the two countries next month.

Kim, the most senior North Korean official to visit the US in 18 years, was seen exiting the Corinthian building in Manhattan at around 8.30 p.m., following a dinner with Pompeo, America’s chief diplomat.

The meeting came as the two sides look to revive the prospects of an on-again off-again summit between US President Donald Trump and North Korean leader Kim Jong Un, originally scheduled for 12 June but later canceled by Trump.

A senior State Department official described Wednesday’s dinner as an opportunity for the two men to strengthen their relationship and discuss preparations.

Prior to Kim’s arrival in New York, White House press secretary Sarah Sanders said that the officials’ “conversation is going to be focused on denuclearization of the peninsula as well as the summit that will take place in Singapore.”

And she added that the administration is still aiming for a June 12 meeting. Referring to denuclearization, Sanders said that, “as long as that is part of the discussion, we’re going to focus on the June 12” date. “We are preparing and expect that to take place on June 12 and if not,” she said, “we’ll be ready on July 12.”

Over the weekend, Kim Jong Un called an impromptu meeting with South Korean President Moon Jae-In at the Demilitarized Zone and reiterated his commitment to denuclearizing.

Pompeo and Kim’s high-level discussions come as a US delegation extended its stay in South Korea “for at least another day,” according to a source familiar with US-North Korean relations.

The US delegation, led by Philippines Ambassador Sung Kim, had been meeting their North Korean counterparts at the Demilitarized Zone since Monday.

Sanders said Wednesday the delegation’s talks along the Korean Demilitarized Zone have been “positive” and that preparation was continuing apace for the summit.

“The readout from these meetings has been positive,” Sanders said.

It’s a remarkable turn-around given that the talks nearly fell apart last week when Trump said he was calling off the June 12 meeting in Singapore. The White House said in a background briefing that North Korean officials hadn’t answered their calls, frustrating their attempts to plan for the meeting.

But they also complained about a senior North Korean foreign ministry official’s comments after he dismissed Vice President Mike Pence as a “political dummy.”

Pence had¬†drawn a comparison¬†between the administration’s hopes for North Korea and the “Libya model,” which could be a reference to starkly different things. It could be read as a way for the country to divest itself of nuclear weapons, or seen as a reference to the overthrowing and killing of Libyan leader Moammar Gadhafi.

Kim Yong Chol is a powerful surrogate for Kim Jong Un. The vice chairman of North Korea’s Party Central Committee, he is the top official in charge of relations between North and South Korea and has been present in all recent high-level meetings with South Korea.

He is also a former head of North Korea’s Reconnaissance Bureau, an espionage and special operations organization. He is believed to have been involved in a torpedo attack that sank the South Korean warship Cheonan in 2010, killing 46 South Korean sailors.

Clarification: This article has been updated to clarify a US delegation is staying in South Korea for at least an extra day. It’s not clear if they will extend their meetings with North Korean officials.
