This book examines the first regional strategy of South Korea toward Southeast Asia and India. At issue is how a middle power (a G20 country with the tenth largest economy in the world) seeks to play a larger and more comprehensive role in regions beyond the Korean peninsula. Hitherto, South Korean foreign policy has focused on nuclearizing North Korea, alliance maintenance with the United States, tricky relations with its most important economic partner China, and difficult ties with Japan marred by historical and territorial disputes. The Moon Administration has sought to diversify South Korean foreign policy by elevating ASEAN and India to the same strategic level as the United States, China, Russia, and Japan. To be sure, the latter countries continue to be most significant to the Korean peninsula. However, this book offers different country and regional perspectives on Seoul’s first regional grand strategy to play a role commensurate with its status as a middle power.
