United Kingdom–South Korea Military Partnership

The United Kingdom and South Korea may be geographically distant, but their military partnership is growing rapidly, driven by regional security concerns, defense technology cooperation, and a shared commitment to global stability. While historically overshadowed by Seoul’s alliances with the U.S., the UK has become an increasingly important defense partner, particularly in maritime security, arms development, and Indo-Pacific strategy. As North Korean aggression and Chinese military expansion reshape regional security, the UK-ROK partnership is emerging as a key pillar of European-Asian defense cooperation.
