A South Korean delegation met with North Korean leader Kim Jong Un on Wednesday in Pyongyang for talks on arranging a third inter-Korean summit planned for this month and to 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 "exchanged opinions" on unspecified issues.
The envoys are planning to fly back to the South after attending a dinner reception hosted by the North. They earlier 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 North's agency that handles inter-Korean affairs, at Pyongyang's Koryo hotel.
South Korean officials said they couldn't provide further details. Moon's office is planning to hold a briefing on the visit on Thursday.
Moon, who discussed his plans with President Donald Trump by telephone on Tuesday, said before the trip that his envoys are tasked with a crucial role at a "very important time" 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 between the countries, or a four-nation meeting that also includes Beijing, to declare a formal end to the 1950-53 Korean War.

The UN 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.
US 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 nukes.
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 wouldn't imply a legally binding peace treaty, experts say it could create political momentum that would make it easier for the North to steer the discussions toward a peace regime, diplomatic recognition, economic benefits and security concessions.
The North has accused the United States of making "unilateral and gangster-like" demands on denuclearization and holding back on the end-of-war declaration.
North Korea's Foreign Ministry on Tuesday published a lengthy statement on its website saying that an end-of-war declaration would be a necessary trust-building step between the wartime foes that would "manifest the political will to establish the lasting and stable peace regime on the Korean Peninsula."
"We will continue to put in efforts so that an end-of-war declaration can be reached by the end of the year. We are always maintaining close communication with the United States."
