North Korea on Thursday threatened to stall the denuclearization of its missile program if the US continues to abide by an "outdated acting script" amid Washington's calls to enforce sanctions against the regime.
The North Korean government said in a statement through its mission to the United Nations that it has halted nuclear missile tests, dismantled a nuclear test site and begun to return the remains of Americans killed in the Korean War, but lamented continued criticism from US officials.
The North Korean statement followed comments this week by top American diplomats stressing the need for Pyongyang to take additional steps toward denuclearisation.
Iranian President Hassan Rouhani told North Korea's foreign minister that the United States can not be trusted, Tehran's state media said, as the United States seeks a deal to rein in the North's nuclear and missile programmes.
Kim vowed in Singapore to work toward denuclearization, but the two sides have yet to define a deal to meet that goal and Washington insists sanctions pressure must be maintained during negotiations.
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.
The report said: "North Korea has not stopped its nuclear and missile programs and continued to defy Security Council resolutions".
"As long as the US denies even the basic decorum for its dialogue partner. one cannot expect any progress in the implementation of the DPRK-US joint statement including the denuclearization", said Pyongyang's foreign ministry, using the initials of the country's official name, warning regional security could suffer.
"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 warned Thursday that there could be no progress in its denuclearization as it accused some senior USA officials of trying to strengthen worldwide sanctions on Pyongyang.
Three South Korean firms were caught importing coal and iron from the North past year, Seoul said Friday (Aug 10), in an apparent violation of United Nations sanctions imposed in August 2017 on the nuclear-armed state.
The rival Koreas plan to hold high-level talks on Monday to prepare for a third summit between their leaders, as Pyongyang called on the United States to reciprocate its "goodwill measures" by easing sanctions and stopping demands that the North denuclearize first.
Washington has said that sanctions will not be lifted until Pyongyang fully and finally dismantles its nuclear weapons.
On Wednesday, US Ambassador to the United Nations Nikki Haley said that the United States was "not willing to wait for too long" for North Korea to take steps towards denuclearising.
