General Studies-2; Topic: Effect of policies and politics of developed and developing countries on India’s interests, Indian diaspora. IntroductionThe ongoing friction in theSouth China Sea (SCS)remains a defining issue of 21st-century geopolitics. The 10th anniversary of the 2016 South China Sea Arbitral Award highlighted growing international concern over China’s unilateral actions and emphasized the importance of a rules-based order for Indo-Pacific security. AboutGeopolitics in the South China SeaThe South China Sea is a critical maritime trade route where China’s expansive territorial claims clash with Southeast Asian nations. Escalating militarization and international legal disputes drive intense global geopolitics. Key Background: The 2016 Arbitral AwardLegal Context:In 2013, the Philippines took China to the Permanent Court of Arbitration (PCA) under the United Nations Convention on the Law of the Sea (UNCLOS). Core Ruling:In 2016, the PCA ruled that China’s historic claim over nearly 90% of the SCS—demarcated by its “Nine-Dash Line”—had no legal basis under UNCLOS. Artificial Islands:The tribunal noted that China’s land reclamation had damaged marine ecosystems and created artificial features that do not confer legal territorial waters. China’s Position:Beijing boycotted the proceedings, declared the judgment “illegal, null, and void,” and refused to implement it, advocating instead for bilateral negotiations with individual claimant states. Recent Strategic DevelopmentsMultilateral Support for Ruling:On the 10th anniversary of the ruling, 14 nations (including the US, Japan, and the Philippines) along with the European Union (EU) issued statements demanding full respect for the 2016 arbitral award and calling for a “Free and Open Indo-Pacific. ”Submarine-Launched ICBM Test:China’s recent launch of an Intercontinental Ballistic Missile (ICBM) from a nuclear submarine in the South China Sea signaled growing military capabilities and an effort to turn the region into a sea-based nuclear bastion. Counter-Alignments:Regional states are responding through multilateral defence partnerships, such as the Australia-Fiji defence pact and expanded India-ASEAN security ties. Multi-Dimensional AnalysisStrategic & Security DimensionPower Projection:Complete control over the SCS allows China to project force directly into the Western Pacific and the Indian Ocean. Nuclear Deterrence Balance:Operating nuclear-powered ballistic missile submarines (SSBNs) in the deep waters of the SCS provides China with a secondary nuclear strike capability, shifting the strategic equilibrium in the Indo-Pacific. Economic & Commercial DimensionGlobal Trade Highway:Over$3 trillion in maritime tradepasses through the South China Sea annually, making it vital for international supply chains. Resource Depository:The seabed contains an estimated 11 billion barrels of oil, 190 trillion cubic feet of natural gas, and rich fishing grounds that feed millions. Legal & Governance DimensionThreat to UNCLOS:By dismissing an international tribunal’s ruling, China sets a precedent where power overrides established international law. Freedom of Navigation:Unilateral maritime restrictions and air-defence identification zones restrict Freedom of Navigation Operations (FONOPs) for other nations. Strategic Implications for IndiaThough India is not a direct party to the SCS disputes, its economic, security, and diplomatic interests are directly tied to the stability of the region:Trade Security:Over55% of India’s sea-borne tradepasses through the South China Sea and the Malacca Strait. Any military conflict in these waters directly threatens Indian trade. Act East Policy:India’s diplomatic engagement with ASEAN relies on a stable, open maritime domain. New Delhi has built security ties with claimant states, such as supplyingBrahMos supersonic missiles to the Philippinesand patrol vessels to Vietnam. Indian Ocean Spillover:As China secures its position in the SCS, its naval deployments into the Indian Ocean Region (IOR) increase. This creates an operational challenge for India along its own maritime frontiers. Normative Alignment:India supports a rules-based order, freedom of navigation, and peaceful resolution of disputes in line with UNCLOS, while referencing the 2016 ruling in joint statements. Strategic Recommendations for IndiaEnhance Maritime Domain Awareness (MDA):Expand surveillance and tracking networks across the Andaman Sea and the broader Indo-Pacific, leveraging Quad partner resources. Expand Security Capacity Building:Continue supporting Southeast Asian states with defence equipment, line-of-credit facilities, and military training to build regional balance. Develop Andaman & Nicobar Infrastructure:Modernize military assets in the Andaman and Nicobar Islands to maintain operational readiness near the western mouth of the Malacca Strait. Support ASEAN Centrality:Work within multilateral frameworks like the East Asia Summit and the ASEAN Regional Forum to promote a binding Code of Conduct (CoC) in the South China Sea that respects UNCLOS. ConclusionIndia must balance its security interests by strengthening ASEAN defence ties, expanding Andaman-Nicobar infrastructure, and upholding UNCLOS to ensure a free, open, and rules-based Indo-Pacific against unilateral Chinese expansionism.
