Last month, Kim and South Korean President Moon Jae-in announced their commitment to the "full denuclearization" of the Korean Peninsula, in their Panmunjom Declaration reached during their April. 27 meeting.
This statement was made by the government in Pyongyang on Sunday, may 6th.
State media said North Korean leader Kim Jong Un attended the celebratory banquet on Saturday for scientists, technicians and officials involved in February 7's launch of a long-range rocket called Kwangmyongsong-4, carrying what North Korea said was a satellite. "What we need is only peace", Moon recently told a group of South Korean officials.
US President Donald Trump, who plans to meet Kim over the next few weeks, has said he will maintain sanctions and pressure on the North and "not repeat the mistakes of past administrations" and has said his tough stance had led to the breakthrough.
"We'll be announcing it soon", Trump told reporters.
Since Kim promised Moon at their summit that he would shut down the Punggye-ri nuclear site in May and invite American and South Korean experts and journalists to inspect the demolition, according to Blue House, that may be on the agenda for the phone conversation.
Preparations for the landmark meeting have gained momentum since the Korean summit late last month, which saw Pyongyang and Seoul promise to pursue the complete denuclearisation of the peninsula and a formal peace treaty to end the 1950-53 Korean War. "The US is also moving to aggravate the situation on the Korean Peninsula by deploying strategic assets on the Peninsula and increasing its attempt of taking up the "human rights" issue against Pyongyang", said the spokesman.
"This act can not be construed otherwise than a risky attempt to ruin the hardly-won atmosphere of dialogue and bring the situation back to square one", the spokesman was quoted as saying. "It's all agreed to", the president said.
He and Kim are expected to meet later this month or early June for discussion on the nuclear standoff between the two countries. "Now I'm trying to calm it down a little bit", he said.
According to the media, Pyongyang has voiced harsh criticism over Japan's support for increased pressure on North Korea. And a lot of things have already happened with respect to the hostages, and I think you're going to see very good things.
The three men - Kim Hak-Song, also known as Jin Xue Song; Tony Kim, also known as Kim Sang-Duk; and Kim Dong-Chul - were seized between 2015 and 2017 and accused of a variety of anti-state offenses.
Japan "will never be able to set foot on (North Korea's) sacred land, even in 100 million years", the paper said in an online commentary.
