Middle Power Constraints and Korea’s Strategic Turn to South Asia
The contemporary international order is increasingly shaped by intensifying geopolitical competition, economic fragmentation, and the growing politicization of interdependence. In this evolving environment, middle powers face structural constraints in projecting influence through traditional forms of hard power. Unlike major powers, they lack the military capabilities and geopolitical leverage necessary to shape outcomes through coercion or dominance. As a result, middle powers must adopt alternative strategies to secure autonomy, expand partnerships, and mitigate external vulnerability.
Korea exemplifies this condition. As a highly industrialized yet resource-dependent economy deeply embedded in global supply chains, it remains particularly exposed to external shocks and geopolitical uncertainty. In response, Korea has pursued a strategy centred on diversification and institutionalization, expanding its diplomatic and economic engagement across multiple regions. In recent years, this outward orientation has increasingly extended toward South Asia, including India, Pakistan, Bangladesh, and Sri Lanka—states that occupy a strategically significant position within the evolving Indo-Pacific order.
Korea’s engagement with these countries reflects a broader transformation in its foreign policy identity as a middle power. Rather than engaging in direct geopolitical competition, Korea emphasizes cooperation, mutual benefit, and long-term partnership. This approach aligns with the strategic preferences of South Asian states, which seek to diversify their external relations and balance their engagement among major powers. Within this context, Korea positions itself as a reliable and non-coercive partner.
Crucially, this engagement is not merely driven by economic opportunity but is also underpinned by a deliberate effort to construct stable and rule-based frameworks of cooperation. By embedding its relations within institutional and legal structures, Korea seeks to ensure predictability, reduce political risk, and sustain long-term partnerships in a region marked by diverse political systems and varying levels of institutional development. This strategic reliance on legal and institutional mechanisms reflects a broader shift in how middle powers exercise influence—prioritizing stability, credibility, and normative alignment over short-term geopolitical gains.
Economic Engagement and the Legal Foundations of Cooperation
Economic cooperation constitutes the most visible and substantive dimension of Korea’s relations with South Asia. India, in particular, has emerged as a central partner, given its large market, expanding industrial base, and growing role in global supply chains. Bilateral frameworks such as the Korea–India Comprehensive Economic Partnership Agreement (CEPA) provide a legal foundation for trade liberalization, investment protection, and economic integration. These institutional arrangements also contribute to aligning regulatory standards and enhancing market accessibility between the two economies.
The Korea–India CEPA, which entered into force in 2010, represents a comprehensive legal framework that goes beyond a traditional free trade agreement by incorporating provisions on trade in goods and services, investment, intellectual property rights, and dispute settlement mechanisms. It includes tariff reduction schedules, rules of origin, and commitments to liberalize key service sectors such as finance, telecommunications, and professional services. In addition, the agreement establishes institutional mechanisms for regular review and dialogue, enabling both parties to address implementation challenges and deepen cooperation over time. These features underscore the role of CEPA not only as a trade facilitation instrument but also as a dynamic platform for long-term economic governance between Korea and India.
More broadly, Korea’s engagement with Pakistan and other neighbouring states is supported by a range of legal instruments, including bilateral investment treaties, double taxation agreements, and intergovernmental arrangements. These legal frameworks reduce uncertainty, protect investors, and create predictable regulatory environments, thereby facilitating long-term economic cooperation—especially in contexts where institutional systems may still be evolving. As a result, they play a crucial role in mitigating political and legal risks that might otherwise deter sustained foreign investment.
Beyond traditional sectors, Korea has expanded its engagement into infrastructure development, manufacturing, and digital transformation. Korean firms have participated in large-scale projects across the region, supported by legal agreements that ensure contractual stability and protect economic interests. In this sense, international law functions not merely as a regulatory mechanism but as an enabling structure that transforms economic opportunities into sustained cooperation. This evolution reflects a broader shift toward technology-driven partnership and deeper economic integration across emerging sectors.
Developmental Diplomacy and Multi-layered Legal Architecture
A defining feature of Korea’s engagement in South Asia is the integration of developmental diplomacy within a legal-institutional framework. Through formal agreements, Korea links official development assistance (ODA), concessional financing, and technical cooperation to broader diplomatic objectives. This approach emphasizes capacity-building, institutional strengthening, and long-term partnership. It also enables Korea to align its development initiatives with the strategic priorities and policy frameworks of partner countries.
In countries such as Bangladesh and Sri Lanka, development cooperation agreements have supported projects in infrastructure, education, and digital governance. The legal codification of these initiatives enhances transparency, accountability, and continuity, ensuring that development cooperation is embedded within structured and sustainable frameworks rather than ad hoc arrangements. This institutionalization further promotes local ownership and increases the effectiveness of project implementation over time.
The cumulative effect of these engagements is the emergence of a multi-layered legal architecture. This architecture can be understood as comprising three interconnected layers: development cooperation agreements, economic and investment treaties, and administrative or sector-specific arrangements. Together, these layers form a comprehensive legal infrastructure that supports sustained engagement and facilitates coordination across multiple domains. Such a structured framework allows for greater policy coherence and reduces fragmentation in bilateral cooperation.
Rather than relying on isolated agreements, Korea constructs a network of mutually reinforcing legal instruments. This reflects a strategic understanding of international law as a mechanism of connectivity and long-term positioning, enabling Korea to build stable and institutionalized relationships across diverse political and economic environments. In this way, legal institutionalization becomes a central pillar of Korea’s broader middle power diplomacy. It also allows Korea to translate legal reliability and institutional credibility into sustained strategic influence in the region.
Future Directions: Law as Strategic Infrastructure in a Multipolar Order
Several emerging trends are likely to shape the future trajectory of Korea’s relations with South Asia. The global energy transition, for instance, is expected to generate new areas of cooperation in renewable energy, green hydrogen, and critical minerals. Legal frameworks governing these sectors will become increasingly important, requiring both the adaptation of existing agreements and the development of new institutional arrangements. In this context, Korea’s ability to proactively shape these legal frameworks will be a decisive factor in securing its long-term strategic and economic interests in the region.
Connectivity and logistics will also play a central role. South Asia’s position within Indo-Pacific and Eurasian trade networks makes it a critical hub for supply chain diversification. Korea is likely to expand its engagement in infrastructure development and regional connectivity initiatives, supported by legal agreements on transit, customs facilitation, and digital trade. Control over and participation in these legally institutionalized connectivity networks will directly influence Korea’s strategic leverage in an increasingly competitive geo-economic environment.
Digital transformation represents another key frontier. Korea’s strengths in information technology and digital governance provide a strong basis for cooperation in areas such as cybersecurity, data regulation, and smart infrastructure. Embedding these areas within formal legal frameworks will deepen institutional linkages and expand the scope of bilateral relations. At the same time, leadership in setting digital rules and standards will enable Korea to shape the normative foundations of the emerging digital order in South Asia.
Ultimately, Korea’s engagement with South Asia illustrates a broader transformation in middle power diplomacy. Influence in the contemporary international system is increasingly constructed through institutional density, legal connectivity, and sustained partnership rather than coercive power. International law, in this context, functions as strategic infrastructure—enabling Korea to pursue diversification, resilience, and long-term strategic positioning in a complex and evolving global order. Far from being a passive tool, legal institutionalization thus becomes an active instrument of power through which Korea can shape regional order and expand its strategic autonomy.
