Despite the criticism, North Korea's Foreign Ministry said the country's leader, Kim Jong-un, still wanted to build on the "friendly relationship and trust" forged with President Trump during their summit meeting in Singapore on June 12.
The statement from North Korea's Foreign Ministry also said Kim Jong Un still holds "feelings of trust" towards President Trump and have said that Kim sent a handwritten letter to Pompeo laying out his position.
The statement was carried by the official KCNA news agency on Saturday soon after Pompeo left Pyongyang, raising questions about the future of talks in which he is trying to persuade Pyongyang to give up a nuclear weapons program that threatens the United States.
The North Korean statement contradicted remarks made by U.S. Secretary of State Mike Pompeo, who said just hours after departing North Korea that the two countries had made progress on several key issues.
"We were able to reaffirm our unwavering commitment to the continued strengthening of our trilateral cooperation toward the common goal of North Korea's complete, verifiable and irreversible dismantlement" of all nuclear weapons and missiles, Japanese Foreign Minister Taro Kono told a joint press conference.
But earlier, in Tokyo, Pompeo said sanctions will remain in place on North Korea "until final, fully verified denuclearization as agreed to by Chairman Kim occurs".
"That was a fairly serious insult directed against Pompeo", said Christopher Hill, who formerly served as USA ambassador to South Korea and lead negotiator with North Korea. At the summit, Mr. Kim committed to complete denuclearization in return for US security guarantees. You asked Pompeo: "'Did he sleep well?' If you knew what I knew about what we could do to the leadership of North Korea, you wouldn't sleep very well", Graham said.
'People are going to make stray comments after meetings, ' Pompeo said. The statement called for a series of simultaneous actions from both sides, including exchanges to improve relations, the dismantling of a North Korean missile-engine testing ground and talks to return the remains of American soldiers killed in the Korean War. But he also had to assuage anxious Asian allies after Trump said he would be stopping U.S.
But following talks on Sunday between US envoy Sung Kim and North Korean counterparts, this "CVID" language appears to have disappeared from the State Department lexicon.
There were concerns from the onset because U.S. President Donald Trump failed to set a concrete framework for denuclearization.
The discoveries have further undercut Trump's assertion that North Korea was "no longer a nuclear threat".
North Korea called the outcome of the discussion "worrisome" and argued that the "cancerous issues" the USA delegation raised were the same ones that had "amplified" distrust and the risk of war with past administrations, resulting in previous talks ending in failure.
He added: "When we spoke to them about the scope of denuclearisation, they did not push back". The White House said before the trip that he would meet Kim.
The North's statement, coming so soon after Pompeo's trip, was sure to fuel growing skepticism in the US over how serious Kim Jong Un is about giving up his nuclear arsenal.
