North Korean leader Kim Jong Un has arrived in Russia to meet with President Vladimir Putin. The meeting is expected to focus on Russia's desire to purchase ammunition from North Korea to replenish its reserves depleted by the war in Ukraine. In return, North Korea is likely to request shipments of food, energy, and sophisticated weapons technologies. This meeting marks Kim's first with a foreign leader since North Korea closed its borders in January 2020. The military cooperation between Kim and Putin could be a cause for concern for rivals such as the US and South Korea.
