Russia's Security Council says a delegation led by former defense minister Sergei Shoigu met with North Korean leader Kim Jong Un in Pyongyang on Friday.

The council said Secretary Shoigu discussed bilateral and international issues with North Korean officials.

The council also said the talks will make an important contribution to the implementation of the Treaty on Comprehensive Strategic Partnership.

The treaty, signed in June during Russian President Vladimir Putin's visit to North Korea, pledges mutual military support in a contingency.

Also on Friday, North Korea's vice foreign minister issued a statement to mark one year since the summit between Kim and Putin at a space center in Russia's Far East.

The statement says North Korea is committed to cooperating with its strategic partner Russia and to developing bilateral relations on a permanent basis.

The United States alleges that Pyongyang is providing ammunition and other military supplies to Russia to be used for Moscow's invasion of Ukraine, and in return is seeking assistance in military technology and energy.
