Trump's comments came after Kim reportedly said his faith in the U.S. president was unchanged and that Pyongyang aimed to achieve denuclearisation within Trump's first term in office, which is due to end in January 2020.
Kim told the South Korean envoys that he is willing to take stronger steps if his "goodwill" measures are met in kind, according to chief envoy Chung Eui-yong.
Progress toward denucleariation of the Korean peninsula appeared to stall in recent weeks following high expectations from Mr. Trump's June summit with Mr. Kim in Singapore.
During his meeting with Kim, Chung delivered a message from Trump and will relay comments from Kim to U.S. National Security Advisor John Bolton, Moon's spokesman, Kim Eui-kyeom, told reporters. "Xi's trip would have taken place at a time when President [Donald] Trump is pointing fingers at China for."[not] helping with the process of denuclearization" due to so-called trade tensions".
U.S. President Donald Trump said on Friday a letter from North Korean leader Kim Jong Un, which he believes will be positive, is on its way to him, a day after expressing fresh optimism about a denuclearization deal.
Kim also continues using the term "complete denuclearization" to suggest he expects American nuclear forces to be withdrawn from striking range of North Korea-a tall order given the very long range of US nuclear forces.
The South Korean delegation came to Pyongyang as U.S.
North Korea's Kim Jong-un wants to realize denuclearization during U.S. President Donald Trump's first term - giving a timeline for the first time - and has agreed to a third summit with his South Korean counterpart, Seoul officials said. Signing a peace treaty without a disarmament deal also carries risks for the US, because it could legitimize Kim's control over half of the peninsula and undermine the rationale for stationing 28,000 or so American troops on the peninsula.
If Kim responded to the outreach, there is a possibility that the Unified Front Department, which is in charge of the country's negotiations with the United States, attempted to explore developments in Japan.
These statements were made during negotiations regarding a summit between North and South Korean leaders, which is expected to take place September 18-20.
Kim did not mention Pompeo's cancelled trip to North Korea, but said he may be able to "more actively" take denuclearization measures should North Korea be given early rewards for the steps it has taken so far, Chung added.
"This trust, despite some difficulties surfaced during the negotiation process between the USA and the North, will continue", Chung said on Thursday, acknowledging the recent unpleasantness. But negotiations have made little progress, while signs North Korea has maintained work on its weapons have emerged.
Kim also cited the dismantling of the Punggye-ri nuclear test site and Dongchang-ri missile launch facility as evidence of his commitment to end nuclear testing permanently, Chung said, The Washington Post reported.
Seoul also wants a trilateral summit among the countries, or a four-nation meeting that also includes Beijing, to declare a formal end to the 1950-53 Korean War.
