North Korea's Foreign Minister Choe Son Hui has arrived in Russia, signaling deepening military cooperation amid reports of 10,000 North Korean troops deployed in support of Russia's war in Ukraine. The Pentagon confirmed this troop increase, noting that some soldiers are moving closer to the Ukrainian front, particularly in the Kursk region. NATO condemned the military ties between North Korea and Russia, calling it a 'significant escalation' that threatens regional security. Choe's visit, described as part of a strategic dialogue initiated during a June summit between Kim Jong Un and Vladimir Putin, raises concerns regarding potential further troop deployments and military technology exchanges. South Korea's intelligence agency has indicated that North Korean military personnel may already be on the frontlines, complicating the conflict dynamics in Ukraine. This situation has prompted strong reactions from U.S. officials, with President Biden labeling it 'very dangerous'.
