leader may go ahead next month.
Crossing the line that separates the two Koreas, Sung Kim met with Choe Son Hui, the North Korean vice foreign minister, who said last week that Pyongyang was "reconsidering" the talks.
"If Kim Yong-chol and Mike Pompeo settleD on a basic draft of their agreement and President Trump accepts it, then that will lead to a confirmation that the summit will take place for sure".
General Kim Yong-chol, 72, has emerged as a key player in North Korean diplomacy in the first half of 2018.
"Solid response to my letter, thank you!"
Kim Yong Chol, 72, is North Korea's former intelligence chief, the vice chairman of North Korea's Party Central Committee, and one of Kim Jong Un's most trusted advisers.
Pompeo's meeting with Kim Yong Chol and the series of discussions this week between U.S. and North Korean officials are the most substantive indication yet that the summit is still in the works despite Trump's letter to Kim Jong Un last Thursday canceling the summit. Since then, Trump has suggested the meeting could be back on.
A North Korean delegation on may 28, will arrive in Singapore to prepare the talks between the DPRK leader Kim Jong-UN and U.S. President Donald trump. The agency said it is "widely expected" that Kim would travel to the US "to reciprocate recent visits" by US Secretary of State Mike Pompeo.
Following an unusually provocative 2017 in which Kim's engineers tested a purported thermonuclear warhead and three long-range missiles theoretically capable of striking mainland USA cities, the North Korean leader has engaged in a flurry of diplomatic activity in recent months.
North Korean leader Kim Jong Un's de facto chief of staff, Kim Chang Son, meanwhile, flew to Singapore via Beijing late on Monday, Japanese public broadcaster NHK reported.
Trump and Abe also reiterated their support for North Korea's complete, verifiable, and irreversible dismantlement (CVID) of its nuclear program. He arrived in Beijing on Tuesday.
American and North Korean officials are also meeting in the Demilitarized Zone with South Korea to discuss a meeting agenda.
White House counselor Kellyanne Conway said Tuesday morning in an appearance on Fox News Channel's "Fox & Friends" that the president had "sent over two delegations - one for logistics and one for more diplomatic purposes that are on the ground making the logistic preparations for June 12".
Despite the North's apparent eagerness for a summit with Trump, there are lingering doubts about whether Kim Jong Un will fully relinquish his nuclear weapons, which he may see as his only guarantee of survival.
He is widely believed to have masterminded the attack on a South Korean naval corvette, the Cheonan, in 2010, leading to the deaths of 46 sailors. The Korean leaders' second summit in a month Saturday, May 26, saw bear hugs and broad smiles, but their quickly arranged meeting appears to highlight a sense of urgency on both sides of the world's most heavily armed border.
While Kim Yong Chol's trip to the United States could further brighten the prospects for the summit, history shows that things could still crumble at the last minute even after an exchange of high-level officials.
But that did not stop North Korea's state media from continuing its criticism of allied military exercises on Tuesday, saying if Washington "sincerely hopes for the talks, it should stop the acts of threatening its dialogue partner by force".
North Korea, in return, would demand the USA normalize its relations with it, ease sanctions against it and remove it from a list of state sponsors of terrorism, which could immediately help the North's economy.
Kim Yong Chol has been a central player in the recent negotiations between North Korea and South Korea, as well as the United States. North Korea and the United States are still technically at war and have no diplomatic ties because the 1950-53 Korean War ended with an armistice, not a peace treaty.
