North Korea has reportedly developed a secret military base near its border with China, potentially housing six to nine nuclear-capable intercontinental ballistic missiles (ICBMs). The Sinpung-dong Missile Operating Base, identified by the Center for Strategic and International Studies (CSIS), is part of an unacknowledged network of facilities aimed at enhancing North Korea’s ballistic missile capabilities. This development poses a significant nuclear threat to East Asia and raises concerns over regional security as North Korea continues to expand its nuclear arsenal following stalled negotiations with the U.S. Furthermore, the increasing collaboration between North Korea and Russia may further exacerbate the geopolitical landscape in the region.
