(CNN) North Korean leader Kim Jong Un told Russian President Vladimir Putin that he believes the United States acted in "bad faith" at the Hanoi summit, North Korean state media reported.

The report in North Korea's state-run KCNA news was released on the final day of Kim's visit to the far-eastern Russian city of Vladivostok. Kim and Putin met there for the first time Thursday , spending about three and a half hours together. The North Korean leader left Vladivostok Friday afternoon aboard his armored government train

KCNA reported that "Kim Jong Un said that the situation on the Korean Peninsula and the region is now at a standstill, and has reached a critical point where it may return to its original state, as the US took a unilateral attitude in bad faith at the recent second DPRK-US summit talks," using the acronym for North Korea's formal name, the Democratic People's Republic of Korea.

KCNA also said Kim told his Russian hosts that "peace and security on the Korean Peninsula will entirely depend on the US' future attitude, and the DPRK will guard itself for every possible situation."
