According to South Korean officials and analysts, Moon hopes for a "comprehensive deal," in which Kim commits to dismantling his nuclear arsenal and Trump reciprocates with security guarantees for the North, including normalised ties and a peace treaty with Washington. Pompeo’s visit and the Tweet provide the strongest sign yet about Trump’s willingness to become the first serving U.S. president ever to meet a North Korean leader, amid a protracted standoff over the North’s nuclear and missile programs it pursues in defiance of U.N. Security Council resolutions. The two sides are due to hold “working-level” talks on Wednesday and then South Korea’s intelligence chief, Suh Hoon, or its national security adviser, Chung Eui-yong, could visit the North to finish off preparations, if deemed necessary, South Korean presidential chief of staff, Im Jong-seok, told reporters. Ahead of a summit next week between North Korean premier Kim Jong Un and South Korean President Moon Jae-in, lawmakers from the neighboring states were thought to be negotiating the details of a joint statement that could outline an end to the confrontation. Trump said he believed there was a lot of goodwill in the diplomatic push with North Korea, but added it was possible the summit - first proposed in March and which the president said could take place in late May or early June - may not happen.

“We expect the summit will confirm the denuclearisation will (of North Korea), and hope to have a comprehensive agreement with the North on the matter.”

Seoul-based university professor John Delury told Bloomberg that negotiating a peace treaty could be as complicated as denuclearization. Trump said earlier on Tuesday the United States was engaged in direct talks at “extremely high levels” with North Korea to try to set up a summit between him and Kim. "We want to include discussions to end hostile acts between the South and North"

South Korea and a U.S.-led U.N. force are technically still at war with North Korea after the Korean War ended with a truce, not a peace treaty.
North Korea and South Korea announce that they are planning to officially end the Korean War by writing a peace agreement. An armistice agreement was reached, ending armed conflict, in 1953. U.S. President Donald Trump called the decision to end the war a blessing.
