According to South Korea, Kim has said he'd be willing to give up his nukes if the United States commits to a formal end to the war and pledges not to attack the North.

SEOUL-North Korea readjusted its time zone to match South Korea's on Saturday and described the change as an early step toward making the longtime rivals "become one" following a landmark summit.

While substantially more bellicose, the Urimininzokkiri op-ed was not the only state-media article published recently which criticized the notion that the USA maximum pressure campaign has led to North Korea's recent diplomatic overtures, with multiple outlets publishing content on the subject over the weekend. To make matters more suspenseful, Trump did not disclose any details of the location or when the meeting will take place.
"This act can not be construed otherwise than a unsafe attempt to ruin the hard-won atmosphere of dialogue and bring the situation back to square one", he added. The South Korean president said in January that Trump "deserves big credit for bringing about the inter-Korean talks".

"We're having very substantive talks with North Korea and a lot of things have already happened with respect to the hostages".
The White House has said its pressure campaign on North Korea will continue until the North dismantles its nuclear program. "What we need is only peace", he said.
"I think you can hope for the best, but we have to prepare for the worst". Mr Trump hinted the release of Kim Dong Chul, Kim Hak Song and Tony Kim was in the offing.
