South Korea reports Russia supplies air defense missiles to North Korea for troop support

South Korea reported that Russia has supplied air defense missile systems to North Korea in exchange for North Korean troops to support Russia's war in Ukraine. This marks a significant development in military cooperation between the two nations. North Korea reportedly sent over 10,000 troops to Russia in October, with some now engaged in combat. South Korean officials believe Russia may have provided advanced missile systems, potentially including S-400 long-range surface-to-air missiles, to enhance North Korea's air defense. The cooperation comes amid rising tensions, with North Korea seeking to improve its military capabilities. Recent agreements between North Korea and Russia also indicate a push for expanded economic cooperation.
