Strategic Imperatives for South Korea under the IPOI

Across prevailing Indo-Pacific frameworks, South Korea’s role has largely been circumscribed by structural constraints. Within the Free and Open Indo-Pacific, Seoul is primarily situated through the prism of the US–ROK alliance, limiting its visibility as an autonomous agenda-setting actor. ASEAN-led mechanisms acknowledge South Korea as a dialogue partner, yet provide limited scope for rule-making influence, while episodic interactions with Quad members have not translated into participation in minilateral core decision-making. Consequently, South Korea’s Indo-Pacific engagement has tended to emphasise contribution within existing structures rather than leadership in shaping them.

India’s Indo-Pacific Oceans Initiative (IPOI) introduces an alternative modality of engagement that is particularly compatible with South Korea’s self-conception as a global pivotal state. Conceived as a functional, non-alliance-based framework, IPOI prioritises issue-specific cooperation and voluntary leadership over strategic alignment. Its design allows capable states to exercise stewardship over discrete domains, thereby shaping norms and practices without being subsumed into bloc politics. For South Korea, engagement at this level would enable a shift from participation as a supporting actor to contribution as a norm-shaper within an emerging Indo-Pacific maritime governance architecture.

This prospect is underpinned by South Korea’s established maritime capabilities. As the world’s second-largest shipbuilder—accounting for approximately 31 per cent of global orders in 2023—South Korea possesses advanced expertise in ship construction, port automation, maritime logistics, and environmentally sustainable shipping technologies. These industrial strengths are complemented by demonstrated competence in disaster preparedness and response, including public health emergencies and flood management. Together, they position South Korea as a credible provider of maritime public goods, aligning closely with IPOI’s emphasis on connectivity, sustainability, and disaster risk reduction.

IPOI also offers a structured pathway for recalibrating South Korea’s geographical engagement within the Indo-Pacific. Despite its significant dependence on the Indian Ocean—through which more than 90 per cent of Korea’s energy imports transit—South Korea’s strategic focus has historically remained concentrated in Northeast and Southeast Asia, often mediated through relations with the United States, Japan, and ASEAN. IPOI facilitates a more direct and visible engagement with the Indian Ocean Region, encompassing South Asia, Africa, and Indian Ocean littoral states where Korea’s strategic presence and normative influence have been comparatively limited.

This geographical expansion assumes added significance in light of the Indian Ocean’s evolving strategic environment. The region has witnessed growing geopolitical contestation, including infrastructure and port development associated with China’s Belt and Road Initiative. IPOI advances a cooperative, development-oriented framework that foregrounds openness, sustainability, and inclusivity rather than competitive alignment. Engagement within this framework allows South Korea to participate as a responsible stakeholder in Indian Ocean governance while avoiding the optics of strategic competition or zero-sum infrastructure rivalry.

The appeal of IPOI for South Korea is further reinforced by its non-confrontational orientation. Unlike security-focused arrangements such as AUKUS, or to some extent the Quad, IPOI emphasises functional cooperation across maritime ecology, disaster management, connectivity, and capacity-building. This distinction is particularly salient given South Korea’s substantial economic interdependence with China, which remains its largest trading partner. IPOI therefore provides a calibrated platform through which South Korea can demonstrate leadership and responsibility in the Indo-Pacific while preserving strategic flexibility and managing economic sensitivities.

This approach is consistent with the Indo-Pacific Strategy articulated under the Yoon Suk Yeol administration, which envisions South Korea as a global pivotal state capable of contributing to norm-setting and public goods provision beyond peninsular security concerns. IPOI offers a practical institutional pathway to translate this strategic narrative into sustained maritime engagement, allowing South Korea to act not merely as an economic partner but as a contributor to regional governance.

The relevance of IPOI engagement is further shaped by recent political developments in South Korea. The appointment of Cho Hyun as Foreign Minister in July 2025—bringing prior experience as Ambassador to India and as Permanent Representative to the United Nations—introduces leadership with direct familiarity with Indian Ocean dynamics and multilateral diplomacy. Such experience strengthens South Korea’s capacity to act as a bridge-builder and norm contributor within cooperative maritime frameworks, reinforcing the credibility of deeper engagement under IPOI.

Taken together, the convergence of South Korea’s maritime capabilities, the functional and inclusive design of IPOI, and a political context receptive to ocean-oriented diplomacy creates favourable conditions for enhanced engagement. IPOI offers South Korea a structured pathway to incrementally expand its role as a responsible stakeholder and norm-shaper in Indo-Pacific maritime governance. In a regional environment increasingly characterised by strategic polarisation, engagement through IPOI enables Seoul to contribute to cooperative, rules-based, and development-oriented maritime practices while remaining consistent with its aspiration to function as a global pivotal state.

Mapping South Korea’s Maritime Interests onto the IPOI Pillars

Among the seven spokes of the IPOI, three align closely with South Korea’s comparative advantages: Science, Technology and Academic Cooperation; Trade, Connectivity and Maritime Transport; and Disaster Risk Reduction and Management. Together, they provide South Korea with clear avenues to exercise leadership in maritime governance while advancing its role as a maritime middle power in the Indo-Pacific.

The Science, Technology and Academic Cooperation spoke offers a natural entry point for South Korea to integrate its innovation-driven economy into ocean governance. With one of the highest research and development expenditures among OECD countries and advanced capabilities in artificial intelligence, robotics, semiconductors, and satellite technologies, South Korea is well positioned to contribute to maritime applications such as vessel traffic management, ocean and climate modelling, maritime domain awareness, and fisheries monitoring. IPOI’s focus on narrowing digital and scientific capacity gaps creates scope for South Korea to support shared data platforms, technical standards, and collaborative research, enabling it to transition from a consumer of maritime data to a contributor to regional digital ocean governance.

The Trade, Connectivity and Maritime Transport spoke aligns with South Korea’s maritime industrial and logistical strengths. As a leading global shipbuilder and home to advanced port infrastructure—exemplified by Busan’s role as a major smart-port hub—South Korea possesses capabilities directly relevant to IPOI’s objective of building resilient and diversified maritime connectivity. Engagement in this domain would allow South Korea to support port modernisation, green shipping, and corridor development across the Indian Ocean, strengthening supply-chain resilience while expanding its maritime presence in regions such as the Bay of Bengal and East Africa.

The Disaster Risk Reduction and Management spoke reflects South Korea’s experience in humanitarian assistance and resilience-building. The Indo-Pacific remains highly vulnerable to natural disasters, placing sustained pressure on coastal and island states. South Korea’s disaster management systems, including early-warning technologies and a well-equipped Coast Guard, along with its track record in regional humanitarian assistance, position it as a credible partner in disaster governance. IPOI-linked initiatives on humanitarian assistance and disaster relief provide a platform for South Korea to contribute through coastal resilience, responder training, and emergency-response capabilities, offering a domain of engagement that is both politically low-risk and regionally visible.

Collectively, these three spokes enable South Korea to project its technological, logistical, and humanitarian strengths beyond Northeast Asia in ways consistent with ASEAN centrality and cooperative regionalism. Engagement across these domains supports a gradual shift in South Korea’s Indo-Pacific role—from that of a primarily economic partner to a contributor to maritime norms, infrastructure, and resilience frameworks shaping the region’s future.

Conclusion

The IPOI represents a functional and inclusive approach to maritime cooperation at a time when the regional landscape is increasingly shaped by strategic competition and institutional fragmentation. By prioritising issue-based collaboration over alignment, IPOI offers a governance framework that addresses shared maritime challenges i.e., connectivity, sustainability, and resilience, while remaining accessible to a diverse range of stakeholders.

For South Korea, IPOI provides a timely and practical platform to align maritime dependence with maritime leadership. Engagement through selected spokes allows South Korea to project its technological, industrial, and humanitarian strengths into the Indian Ocean and wider Indo-Pacific in ways that are consistent with its aspiration to function as a responsible middle power and norm contributor. Rather than duplicating existing mechanisms, IPOI complements South Korea’s Indo-Pacific strategy by offering avenues for leadership that are cooperative, development-oriented, and politically calibrated.

More broadly, South Korea’s participation would reinforce IPOI’s credibility as a genuinely multilateral initiative and underscore the role of middle powers in shaping maritime governance through public goods provision and institutional capacity-building. In an Indo-Pacific environment characterised by both strategic uncertainty and shared vulnerabilities, sustained engagement through frameworks such as IPOI offers a pragmatic pathway to strengthening regional maritime order while preserving strategic flexibility.
