South Korea and the European Union have condemned North Korea for deploying troops to aid Russia in its war against Ukraine, expressing concerns over potential exchanges of sensitive technology that could bolster North Korea's nuclear capabilities. The deployment, confirmed by the U.S. and NATO, is seen as a violation of U.N. Security Council resolutions and a significant escalation in the conflict. Reports indicate that North Korean troops have already engaged in combat in Russia's Kursk region, where Ukraine has launched attacks. This development has raised security concerns internationally, with South Korea and the EU calling for the immediate withdrawal of these troops. Meanwhile, Russian President Vladimir Putin and North Korean Foreign Minister Choe Son Hui have met in Moscow, although details of their discussions remain undisclosed. Militarily, there have been instances of North Korean troops mistakenly firing on Russian soldiers, highlighting the complexities and potential risks of their involvement in the conflict.
