Both India’s and South Korea’s strategic choices are deeply influenced by the rapidly evolving Indo-Pacific construct, particularly amid a mounting U.S.-China rivalry. With India’s “Look/Act East” policy and South Korea’s “New Southern Policy” offering a perfect stage for deepened mutual cooperation, both nations need to further their relations to build Asia’s future while advancing their respective national interests. With both countries following stringent foreign policies as a result of the actions of their immediate neighbors, they present a geopolitically strategic complementarity for their relationship to prosper and emerge as one of the most important relationships in the region. Seoul’s hesitation to overtly embrace the “Indo-Pacific” concept is not really a barrier; rather a geo-political overture to discard the balance of power politics and pursue an autonomous foreign policy. India’s preference for the “Indo-Pacific” is equally based on strategic autonomy, imbibing universal values and an inclusive regional order. Both countries emphasize a free and rules-based Indo-Pacific and have immense potential to establish security and connectivity partnerships as the keystone of their bilateral ties. With India and South Korea understanding the economic importance versus security ramifications of China, and with Japan’s reemergence as a key regional, if not global actor, both countries need to bring serious strategic intent to their relationship. Making use of the ASEAN platform and bilateral dialogues, South Korea and India have the potential to become one of the strongest Indo-Pacific partners of the 21st century.
