STORY: Russian President Vladimir Putin has "gratefully accepted" Kim Jong Un's invitation to visit North Korea, after the pair held a rare summit in Russia's Far East.

Kremlin spokesperson Dmitry Peskov confirmed the invitation on Thursday (September 14), saying Russia intended to build good relations with its neighbor.

He added that Russian Foreign Minister Sergei Lavrov was expected to visit Pyongyang next month.

The summit has stoked U.S. concerns that a revived Moscow-Pyongyang axis could bolster Russia's military in Ukraine and provide Kim with sensitive missile technology.

In Wednesday's talks, Kim and Putin discussed military matters, the war in Ukraine and Russian help for North Korea's satellite program.

Washington has accused North Korea of providing arms to Russia, but it is unclear whether any deliveries have been made.

Both countries have denied those claims.

North Korea is believed to have a large stockpile of artillery shells and rockets compatible with Soviet-era weapons, as well as a history of producing such ammunition.

Amid artillery battles in Ukraine, Russia has ramped up its shell production.

But a North Korean supply line could be useful.

The U.S. State Department said the Biden administration "won't hesitate" to impose additional sanctions on Russia and North Korea if they conclude any new arms deals.
