He continued to note that the US has no current plans to relax sanctions on North Korea until there is evidence the country is taking steps to denuclearize, saying the Trump administration would continue its campaign of "maximum pressure".
A statement from the nation's Foreign Ministry said that following President Trump's June summit with North Korean leader Kim Jong Un, the North has worked to improve relations between the two countries and "make active contributions to peace, security, and prosperity on the Korean Peninsula and over the world".
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.
"We expect the Russians and all countries to abide to the U.N. Security Council resolutions and enforce sanctions on North Korea", he said.
The North Korean statement followed comments this week by top American diplomats stressing the need for Pyongyang to take additional steps toward denuclearization.
Bolton, in an interview on Fox News, said U.S. Secretary of State Mike Pompeo was prepared to return to North Korea for another meeting with Kim. It also claims that "high-level officials within the USA administration are making baseline allegations against [North Korea] and making desperate attempts at intensifying the worldwide sanctions and pressure".
A statement from the North Korean government, broadcast via the Korea Central News Agency, accused USA figures of spouting "falsehoods" about the North Korean nuclear issue.
Earlier this month, U.S. Secretary of State Mike Pompeo warned Russia, China and other countries against any violation of worldwide sanctions on North Korea that could reduce pressure on the North to abandon its nuclear weapons.
North Korea has condemned the U.S. for placing fresh sanctions on it and called on the country to respond to its efforts to improve bilateral ties.
"This is all in North Korea's court", Haley told reporters traveling with her during a visit to Colombia, where she attended the inauguration of new Colombian President Ivan Duque and met migrants who had fled Venezuela.
North Korea's nuclear weapons program has caused global tension for decades and the rhetoric and threats from Kim and Trump had been especially hostile before their June meeting.
