It also marked Kim's first visit abroad since the Hanoi summit in February with the President of the US, Donald Trump, which ended abruptly without an agreement on the denuclearization process that was underway.

On Friday, KCNA published comments made by Kim during the meeting with Putin in which he blamed the US for the failure of the summit at Hanoi for maintaining a unilateral position and warned that his country was prepared for any possible situation.

Putin expressed his support for the need to offer security guarantees in exchange for disarmament by Pyongyang, consistent with the position of another important partner of the North Korean regime.

Putin said that Pyongyang only needed security guarantees, and that it would require the US to show its desire for a constructive dialog.

Putin is an advocate of reviving six-party talks - consisting of China, North Korea, South Korea, the US, Japan and Russia - to ensure Pyongyang gets security guarantees in return for disarmament.
