India’s Strategic Interests and Diplomatic Posture in the South China Sea Dispute: Navigating Law, Stability, and Regional Power Shifts
Abstract
India’s engagement with the South China Sea (SCS) dispute reflects a calibrated strategy rooted in its commitment to freedom of navigation (FoN), international maritime law, and regional stability. Although India is not a direct claimant in the maritime disputes involving China, Vietnam, the Philippines, Malaysia, and Brunei, it maintains substantial economic and strategic stakes in the region. Through its Act East Policy, expanding defense cooperation with ASEAN, and participation in naval exercises and multilateral forums, India aims to assert a normative and strategic presence while balancing the implications of China’s assertiveness. This essay analyzes India’s interests, responses, and strategic posture in the South China Sea, and situates them within the larger framework of its Indo-Pacific strategy and the emerging regional order.
1. India’s Core Interests in the South China Sea
1.1. Freedom of Navigation and Commercial Interests
India is a major stakeholder in sea lane security:
- More than 55% of India’s trade passes through the South China Sea and the Malacca Strait.
- The region is critical for energy imports, including shipments from East Asia, Australia, and the Middle East.
Hence, unhindered access to maritime commons is essential for India’s economic security and regional integration.
1.2. Adherence to International Maritime Law and UNCLOS
India is a strong proponent of the United Nations Convention on the Law of the Sea (UNCLOS) as the normative framework for maritime governance:
- India affirms that freedom of navigation, overflight, and lawful commercial activities must be protected under UNCLOS.
- It has consistently opposed unilateral actions, particularly those that alter the status quo without legal or multilateral legitimacy—implicitly criticizing China’s expansive “nine-dash line” claims.
India supported the 2016 Permanent Court of Arbitration ruling in favor of the Philippines, though it did so cautiously to maintain strategic balance.
2. Strategic Posture and Balancing Act
India’s response to the South China Sea dispute is characterized by strategic ambiguity and calibrated engagement:
- It avoids explicit alignment with any claimant state, focusing instead on normative principles and regional cooperation.
- Simultaneously, India engages in defense diplomacy and capacity-building with affected states, projecting a form of soft balancing against China’s maritime assertiveness.
3. Act East Policy and ASEAN Engagement
3.1. Evolution from Look East to Act East
India’s Act East Policy, launched in 2014, reoriented its Southeast Asian engagement toward a more proactive and strategic role:
- The policy emphasizes economic integration, political engagement, and security partnerships with ASEAN countries and East Asian powers.
- In the maritime domain, it aligns closely with Indo-Pacific connectivity and security objectives.
3.2. Defense Cooperation with ASEAN Claimants
India has expanded defense and maritime partnerships with countries directly involved in the South China Sea dispute:
- Vietnam: A key partner in India’s maritime outreach. India has provided naval patrol vessels, offered lines of credit for defense acquisition, and participated in bilateral naval exercises.
- Philippines and Indonesia: Cooperation in capacity-building, hydrographic surveys, and disaster response.
- India supports freedom of navigation patrols, although without directly participating in U.S.-style FONOPs (Freedom of Navigation Operations).
India’s bilateral defense engagements enhance the maritime capabilities of Southeast Asian countries, thereby indirectly countering Chinese coercion.
4. Naval Exercises and Maritime Diplomacy
4.1. Naval Presence and Interoperability
India’s maritime diplomacy includes regular naval deployments and participation in joint exercises:
- SIMBEX (Singapore), INDINDO (Indonesia), and CORPATs (coordinated patrols) reflect bilateral security commitments.
- Participation in Malabar exercises (with the U.S., Japan, and Australia), and in multilateral exercises like RIMPAC and MILAN, increases India’s visibility and integration with Indo-Pacific partners.
- Mission-based deployments in the South China Sea and Western Pacific signify India’s resolve to uphold regional maritime stability.
4.2. Port Calls and Logistics Agreements
India has signed logistics support agreements with countries like Singapore, Vietnam, and the Philippines, enabling greater naval reach and operational sustainability in the region.
These engagements reinforce India’s profile as a security provider and responsible maritime power.
5. Strategic Challenges and Diplomatic Balancing
5.1. Managing China’s Assertiveness
India’s South China Sea policy is significantly shaped by its border tensions and strategic rivalry with China, particularly after the Galwan clash (2020):
- India seeks to avoid an overtly confrontational stance in the South China Sea to prevent escalation on the Himalayan front.
- However, it is gradually tightening strategic partnerships and deepening alignment with Quad countries and ASEAN states.
India’s balancing act reflects a multi-aligned yet autonomous posture, emphasizing both strategic deterrence and diplomatic prudence.
5.2. ASEAN Centrality and Multilateral Engagement
India upholds ASEAN centrality in regional frameworks:
- It participates in the East Asia Summit (EAS), ASEAN Defence Ministers Meeting-Plus (ADMM+), and the ASEAN Regional Forum (ARF).
- India supports ASEAN’s Code of Conduct negotiations with China, stressing that any agreement must be consistent with UNCLOS and non-prejudicial to third parties.
This multilateral engagement reinforces India’s image as a neutral but constructive stakeholder.
6. Implications for India’s Indo-Pacific Strategy
India’s posture in the South China Sea complements its broader Indo-Pacific vision:
- India’s Indo-Pacific Oceans Initiative (IPOI) promotes maritime security, connectivity, disaster resilience, and resource sustainability.
- Through platforms like Quad and IORA, India contributes to shaping a multipolar and rules-based maritime order.
- Its calibrated involvement ensures that India does not cede the strategic maritime space to China, while maintaining flexibility and normative legitimacy.
The South China Sea thus serves as a testing ground for India’s multi-vector diplomacy, maritime assertiveness, and strategic restraint.
Conclusion: A Principled Stakeholder with Strategic Prudence
India’s approach to the South China Sea dispute reflects a complex interplay of normative commitment, strategic interest, and diplomatic balance. While not a claimant, India has a legitimate stake in maintaining freedom of navigation, adherence to UNCLOS, and regional stability. Through its Act East Policy, naval diplomacy, and multilateral engagement, India positions itself as a proactive, rules-based maritime actor committed to a free, open, and inclusive Indo-Pacific.
As China continues to challenge international maritime norms, India’s strategic engagement—marked by both assertive presence and careful restraint—will remain central to shaping the regional order and reinforcing its own credentials as a responsible power and a guardian of the global commons.
