Following his latest visit to Pyongyang, U.S. Secretary of State Mike Pompeo denied Sunday in Tokyo that Washington has softened its stance against North Korea, saying the U.S.is still demanding "complete, verifiable and irreversible denuclearization (CVID)" of the nuclear-armed hermit state.
A letter from Kim to Trump was also delivered to Pompeo through Kim Yong Chol, a top North Korean party official and former spy agency chief, who was Pompeo's interlocutor and played a key role in arranging the Singapore summit.
The tough statement comes hours after Pompeo said progress with North Korea had been made "on nearly all of the central issues" including denuclearisation, although he insisted that work still needed to be done.
"We expected that the U.S. side would come with productive measures conducive to building trust in line with the spirit of the North-U.S. summit and (we) considered providing something that would correspond to them", the spokesman said.
"First, let's get a wrap up of Secretary Pompeo's meeting in Pyongyang, and what we know so far". One US senator pointed a finger at China for encouraging North Korea to be tougher. He stressed there was still more work to be done in other areas, much of which would be done by working groups that the two sides had set up to deal with specific issues.
She wouldn't characterize Friday's discussions beyond saying they addressed denuclearization and the repatriation of American remains, saying, "We expect them to live up to their commitments". Trump pledged a halt to large-scale military drills with South Korea during denuclearization talks with North Korea.
Mr. Pompeo said he spent "a good deal of time" discussing a denuclearisation timeline and the declaration of the North's nuclear and missile facilities. He did not reply when a reporter asked him at the start of that breakfast meeting to respond to North Korea's statement. According to the report, North Korea may be intentionally trying to "deceive the U.S." by continuing these efforts in secret facilities.
Pompeo called on North Korean leader Kim Jong Un to replicate Vietnam's "miracle" of economic growth by improving ties with the USA, vowing that America keeps its promises with former foes.
"It's part of our discussions each and every time we interact with our North Korean counterparts", Pompeo told the press conference with Kono and South Korea's Kang, who also said the issue is of concern to Seoul.
A state department spokesperson said Pompeo had been very firm in focusing on denuclearisation, and other security assurances, BBC reported.
Pompeo, however, said more talks were needed on both.
"I am convinced that he understands the commitment he made, and I am hopeful we will find a path forward to achieve that commitment that Chairman Kim himself made personally to President (Donald) Trump, and the world, in a signed agreement".
Pompeo and Kim met for almost three hours Friday and then had dinner amid growing skepticism over how serious Kim Jong Un is about giving up his nuclear arsenal and translating the upbeat rhetoric following his summit with Trump into concrete action.
Richard Haass, president of the Council on Foreign Relations, said on Twitter there was a danger of military action because Trump might now claim he had tried diplomacy but was betrayed by Kim.
