South Korean President Moon Jae-in announced North Korean leader Kim Jong-un has requested to hold another summit with US President Donald Trump soon in order to move along Pyongyang's process of denuclearisation.
Mr Moon proposed the compromise at a press briefing in Seoul after a three-day visit to North Korea.
Pyongyang also said it could dismantle its best-known nuclear facility at Yongbyon, if the U.S. takes "corresponding measures", as Kim and the South Korean president held their third summit this year. South Korea and the United States remain technically at war with North Korea because the 1950-53 Korean War ended in an armistice and not a peace treaty.
The declaration, published by South Korea's presidential office, states that Seoul and Pyongyang share the view that the Korean Peninsula "must be turned into a land of peace free from nuclear weapons and nuclear threats, and that substantial progress toward this end must be made in a prompt manner". He didn't indicate in his brief remarks whether the US would be willing to take further steps to encourage North Korean action on denuclearization.
The 2,744-metre (9,003-foot) peak is considered sacred by all Koreans as the birthplace of Dangun, the legendary founder of the first Korean kingdom.
As Moon arrived at an airport near the mountain, some 1,000 North Koreans greeted him, waving flowers and chanting "Motherland!"
The two leaders also agreed to pursue a bid to co-host the 2032 Olympic Games, and Moon said he expects Kim Jong-un to soon become the first North Korean leader to ever visit Seoul.
In addition, he invited North Korean representatives to meet with U.S. Special Representative for North Korea Stephen Biegun in Vienna, Austria, "at the earliest opportunity". His parents had fled from the North during the war, sailing for three days on the deck of a US ship packed with refugees.
Many South Koreans also feel drawn to the volcano, which, according to Korean mythology, was the birthplace of Dangun, the founder of the first ancient Korean kingdom, and has always been considered one of the most lovely places on the peninsula. Experts say the destruction of the missile engine test site and launch pad wouldn't represent a material step in the denuclearization of North Korea, which declared its nuclear force complete a year ago and has designed its most powerful missiles to be fired from vehicles.
Kim's decision to dismantle its key missile site at Dongchang-ri in the presence of global observers is what Pompeo said prompted his decision to make the invitation.
The Captain Marvel trailer pulls off something awesome
Whatever the case, it's clear that Captain Marvel is one of the most exciting additions to the MCU yet. A younger Nick Fury's (Samuel L Jackson's) narration is about "war being a universal language".
Despite the doubts of U.S. officials and outside analysts, North Korea's pledge at the summit with the South Korean president drew an enthusiastic response from Trump.
While Kim didn't commit Wednesday to giving up his arsenal of nuclear weapons and ballistic missiles that pose a threat to the US mainland, he did promise to dismantle North Korea's main rocket launch site in the presence of global experts, and offered to shutter its Nyongbyon nuclear site.
"We absolutely can not let this hard to come by opportunity for peace slip away once again", the Chinese government's top diplomat, State Councillor Wang Yi, said in a statement.

"I have a dream that I have not been able to fulfil for a long time, which is trekking Mount Paektu", Moon said at the time.
Nevertheless, Kim has already made the Trump administration back off from military exercises and from the "Libyan model" of rapid denuclearisation, observers say.
A former human rights lawyer, he said in a 2017 book published months before his election as president that he wanted to "finish his life" in his mother's North Korean hometown doing pro-bono service.
Speaking ahead of Mr Pompeo's announcement, Mr Trump welcomed Mr Kim's pledges, calling them part of "tremendous progress" with Pyongyang on a number of fronts, and hailing "very good news" from the summit between the Koreas.
Washington meanwhile is still demanding concrete action towards denuclearisation, such as a full disclosure of North Korea's nuclear and missile facilities, before agreeing to key goals of Pyongyang.
