In this photo from March 5, 2018, provided by the North Korean government, North Korean leader Kim Jong Un, second left, meets members of South Korean delegation headed by National Security Director Chung Eui-yong, center in right row, in Pyongyang, North Korea. Chung added that the two Koreas had also agreed to set up a hotline between Moon and Kim, and they will have their first phone call after the summit.
The apparent diplomatic breakthrough came after the first ever high-level meeting between Kim and a South Korean delegation Monday in the North's capital, Pyongyang.
The United States presented the request on February 23 to a UN sanctions committee as part of a crackdown on smuggling of North Korean commodities, in violation of UN sanctions resolutions.
Perhaps most surprising was Chung's claim that North Korea had expressed an openness to holding a "candid dialogue" with the United States over nuclear disarmament demands. The U.S. has until now largely been skeptical of the North's intentions, citing past agreements that led to a freeze in the nuclear program in exchange for aid but ultimately broke down.
In 2009, the United Nations Security Council responds to a North Korean missile test by threatening to increase sanctions and Pyongyang, which had balked at verification efforts, says it will no longer participate in the six-party talks.
In May 2008, North Korea demands the United States remove it from its list of state sponsors of terrorism and Washington complies in October, prompting the North to resume tearing down its Yongbyon nuclear plant.
North Korea is reportedly willing to give up its nuclear weapons program if safety can be guaranteed for Kim Jong Un's regime, according to South Korea.
Trump tweeted: "Possible progress being made in talks with North Korea".
China on Friday "placed a hold on the proposals" from the United States, said the Dutch chair of the sanctions committee in a letter seen by AFP.
But while this is a new gambit for Kim, it is not new for the North Korean regime.
It will be the third meeting between the leaders of North and South, but the first to take place in the DMZ after summits in Pyongyang in 2000 and 2007.
As Reuters writes: "The United States, which stations 28,500 troops in the South, a legacy of the Korean War, denies any such plans".
Though surprising, the statements from North Korea aren't a complete u-turn.
The Koreas are to hold working-level talks ahead of the summit between Kim and liberal South Korean President Moon Jae-in.
"The dinner proceeded in a warm atmosphere overflowing with compatriotic feelings", the North's official Korean Central News Agency said in a report, one of several that mentioned the Koreans' shared blood and implied that they were united together against the outside world.
North Korea also promised not to use any of its weapons against South Korea.
Nonetheless, Trump added that a "serious effort" to ease regional tensions and rid the Korean peninsula of nuclear weapons is being made by all sides. Chung will later visit China and Russian Federation, while Suh Hoon, the head of South Korea's spy agency and another member of the delegation, will head to Japan.
