The South China Sea (SCS) is a critical geopolitical hotspot, and despite not being a littoral state, India has significant and growing economic, maritime, and strategic interests in the region. These interests are driven by India's energy security needs, trade routes, 'Act East' policy, and broader regional stability concerns.

1. Economic Interests:

• Energy Security: A substantial portion of India's energy imports, particularly crude oil and natural gas, passes through the South China Sea. India is heavily reliant on these sea lanes of communication (SLOCs) for its economic sustenance. Any disruption or instability in the SCS could severely impact India's energy supply and economic growth.
• Trade Routes: Over 55% of India's trade with the Indo-Pacific region, including East Asia, Southeast Asia, and Australia, transits through the SCS. This includes trade with major partners like Japan, South Korea, and ASEAN countries. Maintaining freedom of navigation and unimpeded commerce is therefore vital for India's economic prosperity.
• Oil and Gas Exploration: India's state-owned oil and natural gas corporation, ONGC Videsh Limited (OVL), has exploration interests in blocks within Vietnam's Exclusive Economic Zone (EEZ) in the SCS. While these ventures have faced challenges due to China's territorial claims, India maintains its right to explore resources in partnership with littoral states, based on international law.
• Investment and Connectivity: India's 'Act East' policy aims to enhance economic engagement and connectivity with Southeast Asian nations. The SCS serves as a crucial maritime bridge for these initiatives, facilitating trade, investment, and infrastructure projects.

2. Maritime Interests:

• Freedom of Navigation and Overflight: India is a strong proponent of the United Nations Convention on the Law of the Sea (UNCLOS) and advocates for freedom of navigation and overflight for all nations in international waters, including the SCS. This principle is fundamental to India's maritime security and economic interests.
• Rules-Based Order: India supports a rules-based international order and peaceful resolution of disputes in accordance with international law. It views any unilateral actions or militarization that challenge these principles as detrimental to regional stability and its own maritime interests.
• Maritime Security: India's growing naval capabilities and its role as a net security provider in the Indian Ocean Region extend to ensuring the safety and security of its maritime trade routes that traverse the SCS. This includes combating piracy, terrorism, and other non-traditional threats.

3. Strategic Interests:

• Regional Stability and Balance of Power: India has a vested interest in maintaining peace and stability in the Indo-Pacific region. The SCS disputes, if escalated, could destabilize the entire region, impacting India's security and economic environment. India seeks a balanced regional architecture where no single power dominates.
• 'Act East' Policy: The SCS is central to India's 'Act East' policy, which seeks to deepen engagement with Southeast Asian and East Asian countries. A stable and open SCS is essential for the success of this policy, fostering stronger diplomatic, economic, and security ties.
• Counterbalancing China's Influence: While not explicitly stated as a primary objective, India's increased engagement in the SCS is also seen in the context of balancing China's growing assertiveness and military presence in the region. India's partnerships with countries like Vietnam, the Philippines, and Japan, and its participation in forums like the Quad, reflect a broader strategy to uphold a free and open Indo-Pacific.
• Naval Presence and Diplomacy: India periodically conducts naval exercises and port calls in the SCS with friendly littoral states, demonstrating its commitment to regional security and its ability to project power. This presence serves as a diplomatic tool and reinforces India's strategic partnerships.

In essence, India's interests in the South China Sea are multifaceted, encompassing the critical arteries of its trade and energy supply, adherence to international maritime law, and the broader strategic imperative of maintaining a stable and balanced regional order in the Indo-Pacific.
