North Korean leader Kim Jong-un has arrived in Russia for talks with Russian President Vladimir Putin. Kim made the journey from Pyongyang to the eastern Russian city of Vladivostok aboard an armored train. Putin is reportedly seeking to purchase stockpiles of North Korean artillery shells and rockets for Russia’s war effort in Ukraine; in exchange, North Korea could receive food, fuel and technology from Moscow.

In Washington, D.C., the State Department threatened new sanctions against Russia and North Korea, saying any such deal would violate multiple Security Council resolutions.
