"We have no speed limit".
North Korean leader Kim Jong Un made a broad commitment to denuclearize at an unprecedented summit with Trump in June, but offered no details as to how and when this might take place, leaving considerable doubts about Pyongyang's intentions.
There is "no rush" on North Korean denuclearization for the USA, at least according to Donald Trump... despite the earlier "maximum pressure" campaign, demanding that Pyongyang start the process "very quickly".
While Trump asserted that North Korea was "no longer a nuclear threat" upon his return from Singapore, North Korea has not publicly confirmed that it has dismantled any of its nuclear weapons or ballistic missile infrastructure since the June 12 meeting.
"... Russian Federation has agreed to help with North Korea, where relationships with us are very good and the process is moving along", Trump wrote.
After Pompeo's visit, North Korea accused his delegation of making "gangster-like" demands in connection with denuclearization.
Pompeo added that talks between the US and North Korea "will be taking place against the backdrop of the continued enforcement of existing sanctions".
"President Putin is going to be involve in the sense that he is with us", Trump said. We have - we're just going through the process.
The president's latest comments on the timeline for denuclearisation appear to shift from his position ahead of the summit with Mr Kim, when he said denuclearisation should start "without delay".
Last month's summit was the first ever meting between leaders of the United States and North Korea.
There are reasons to think Russian Federation is at least somewhat amenable to the idea of denuclearizing North Korea, and they might want it badly enough to stick with the program even if the US refuses to be shaken down for additional concessions.
The North Korean officials were being recalled for a possible ambassadorial meeting, according to South Korea's Yonhap News Agency.
