But, following the meeting, US intelligence officials said they believed North Korea was "deceiving" the USA, saying the regime was bolstering production for nuclear weapons at "multiple secret sites" in recent months. Notably, the statement didn't directly criticize Trump.
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.
The stark comments come after Trump and Kim's June meeting in Singapore, during which the White House said the North had made firm pledges to rid itself of its nuclear weapons.
"However, the United States responded to our expectation by inciting global sanctions and pressure against the DPRK", it said in a statement carried by KCNA news agency. North Korea also accused unidentified high-level USA officials of "going against the intention of President Trump" by "making baseless allegations against us and making desperate attempts at intensifying the worldwide sanctions and pressure". Last month, Washington warned against loosening sanctions on Pyongyang after Russian Federation and China suggested discussing such a move.
The unidentified spokesperson also warned that there is no guarantee that the hard-won atmosphere of stability on the Korean Peninsula will continue. Among the agreements was holding another inter-Korean summit in the fall in Pyongyang.
"We hoped that these goodwill measures would contribute to breaking down the high barrier of mistrust existing between the DPRK (North Korea) and the USA and to establishing mutual trust", it said in a statement carried by the North's KCNA news agency.
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. The United States cancelled a joint war exercise with South Korea that was due to take place this month while dismissing calls to ease sanctions until the North delivers on its commitments to fully denuclearize.
Seoul said it accepted the North's proposal after Pyongyang first suggested a meeting Monday to discuss another summit between the leaders. It also wasn't clear when another leaders' summit might happen.
In the meantime, both Koreas are seeking an end of the Korean War.
Pyongyang has also stepped up its calls for a formal end to the Korean War, which some analysts believe is meant to be the first step in the North's effort to eventually see all 28,500 USA troops leave the Korean Peninsula.
The Korean Peninsula is still technically in a state of war because the 1950-53 fighting ended with a ceasefire, not a peace treaty.
Trump's national security adviser, John Bolton, also said this week that North Korea has not taken the steps necessary to denuclearise. But across the region, there have been signs that U.S. President Donald Trump's campaign for "maximum pressure" lost steam after Pyongyang sought to improve relations with Washington, Seoul and Beijing.
