A South Korean delegation met with North Korean leader Kim Jong Un on Wednesday during a visit to arrange an inter-Korean summit planned for this month and help rescue faltering nuclear diplomacy between Washington and Pyongyang.

The office of South Korean President Moon Jae-in said the envoys led by his national security adviser delivered his personal letter to Kim and โ€œexchanged opinionsโ€ on unspecified issues.

It wasnโ€™t immediately clear whether the Korean officials fixed a date for a third summit this year between Moon and Kim or made any progress in breaking an impasse in talks between North Korea and the United States over dismantling Kimโ€™s nuclear weapons program. When asked whether the meeting with Kim went well, Moon spokesman Kim Eui-kyeom said he didnโ€™t know.

The envoys flew back to South Korea after attending a dinner reception hosted by the North. Earlier on Wednesday, they met Kim Yong Chol, a former spy chief who has been negotiating with the United States on nuclear issues, and Ri Son Gwon, chairman of the Northโ€™s agency that handles inter-Korean affairs, at Pyongyangโ€™s Koryo hotel.

South Korean officials said they couldnโ€™t provide further details. Moonโ€™s office is planning to hold a briefing on the visit on Thursday.

Moon, who discussed his plans with U.S. President Donald Trump by telephone on Tuesday, said before the trip that his envoys were tasked with a crucial role at a โ€œvery important timeโ€ that could determine the prospects for lasting peace on the Korean Peninsula.

While pushing ahead with summits and inter-Korean engagement, Seoul is trying to persuade Washington and Pyongyang to proceed with peace and denuclearization processes at the same time so they can overcome a growing dispute over the sequencing of the diplomacy.

Seoul also wants a trilateral summit among the countries, or a four-nation meeting that also includes Beijing, to declare a formal end to the 1950-53 Korean War. The U.N. General Assembly in late September would be an ideal date for Seoul, but many analysts see that possibility as low, considering the complications of the process and how far apart the parties currently are.

U.S. officials have insisted that a peace declaration, which many see as a precursor to the North eventually calling for the removal of all U.S. troops from the Korean Peninsula, cannot come before North Korea takes more concrete action toward abandoning its nuclear weapons. Such steps may include providing an account of the components of its nuclear program, allowing outside inspections and giving up a certain number of its nuclear weapons during the early stages of the negotiations.

While an end-of-war declaration wouldnโ€™t imply a legally binding peace treaty, experts say it could create political momentum that would make it easier for North Korea to steer the discussions toward a peace regime, diplomatic recognition, economic benefits and security concessions.
