TOKYO - North Korean leader Kim Jong Un will visit Russia "soon" for a summit with Russian President Vladimir Putin, North Korea's state media reported Monday.

Kim's visit is at the invitation of Putin, according to the official Korean Central News Agency. Sources close to Russian authorities said a train carrying Kim left Pyongyang for Russia and that he and Putin are likely to hold talks on Tuesday evening.

The two last held talks in Vladivostok in April 2019.

Putin has arrived in Vladivostok to attend a three-day economic forum from Sunday, Tass reported.

The sources said Kim, who rarely travels outside his country, will likely stay in Russia through Wednesday.

The New York Times reported last week that the two leaders would meet to discuss the possibility of supplying Russia with weapons as well as other military cooperation. This comes as Russia struggles in its invasion of Ukraine launched in February 2022.

The United States has warned North Korea not to provide weapons and ammunition to Russia for use against Ukraine.
