"It's just North Korea that has not taken the steps we feel are necessary to denuclearize". Russian Federation and China have suggested the U.N. Security Council could discuss loosening sanctions on Pyongyang after the June 12 Singapore meeting between Trump and Kim.
A foreign ministry spokesman said in a statement on state-run KCNA that North Korea was still willing to institute the broad agreement reached at the June 12 summit meeting in Singapore between US President Donald Trump and North Korean leader Kim Jong-un.
North Korean Foreign Minister Ri travelled this week to Iran, where President Hassan Rowhani told him the United States could not be trusted after the Trump administration reneged on a 2015 deal to lift sanctions in return for curbs on Iran's own nuclear programme.
The US has insisted it is vital to maintain diplomatic and economic pressure on the North.
North Korea on Thursday accused the United States of acting in bad faith, saying Washington's push for full sanctions pressure against Pyongyang would stall progress on the denuclearisation of the Korean Peninsula. Pompeo's comments came on the heels of a United Nations report that found North Korea has not stopped its nuclear and missile programs and is violating U.N. sanctions, including through illicit ship-to-ship transfers of oil.
Last month, North Korea accused the USA of using "gangster-like" tactics in the negotiations.

The Iran-backed rebels have in recent months ramped up missile attacks against Saudi Arabia, most of which are intercepted. Houthi media broadcast gruesome footage appearing to show the dead bodies of children. "Grotesque, shameful, indignant.
North Korea also accused unidentified high-level U.S. officials of "going against the intention of President Trump" by "making baseless allegations against us and making desperate attempts at intensifying the global sanctions and pressure".
The ministry added that expecting "any result" to negotiations in this context was "indeed a foolish act that amounts to waiting to see a boiled egg hatch out". "We have to see denuclearization and we're not going to stop until we get it".
The statement comes days after the USA stressed the need to keep up pressure on Pyongyang through tough sanctions imposed over its nuclear weapons programme.
Pyongyang's Foreign Minister Ri Yong-ho is now on a visit to Iran where President Hassan Rouhani warned the USA could not be trusted after Tehran's experience of having the Trump administration tear up an Obama-era deal to ease sanctions.
"Since we know that the U.S. will never give up its hostile policy toward us, we will hold onto our nuclear knowledge", he was quoted by local media.
