The South China Sea (SCS) is a marginal sea of the Western Pacific Ocean, bordered by China, Taiwan, the Philippines, Vietnam, Malaysia, and Brunei. In recent years, it has transformed into a global flashpoint due to overlapping territorial claims and China’s aggressive maritime posturing. For UPSC aspirants, understanding the SCS is vital as it sits at the heart of the Indo-Pacific construct.
Background: The Roots of Conflict
The dispute is rooted in historical and legal claims. The most contentious is China’s Nine-Dash Line, a U-shaped boundary first proposed in 1947 that claims nearly 90% of the sea.
- Historical Claims: China cites “ancient maritime rights,” while Vietnam claims sovereignty over the Paracel and Spratly Islands based on 17th-century administration.
- Geographical Proximity: The Philippines and Malaysia base their claims on proximity and the legal framework of Exclusive Economic Zones (EEZ).
Key Stakeholders
- Claimants: China, Vietnam, Philippines, Malaysia, Brunei, and Taiwan.
- Non-Claimant Players: * United States: Focuses on Freedom of Navigation Operations (FONOPS).
- ASEAN: Seeks a legally binding Code of Conduct (CoC).
- India: Interested in a rules-based international order and trade security.
Strategic and Economic Importance
The SCS is one of thost vital waterways in the world:
- Trade Route: Over one-third of global shippe ming passes through this region.
- Natural Resources: Estimates suggest 11 billion barrels of oil and 190 trillion cubic feet of natural gas reserves.
- Fisheries: The sea accounts for roughly 10% of the global fisheries catch, essential for regional food security.
Recent Developments (2024-25)
- Aggressive Posturing: Frequent clashes between the Chinese Coast Guard and Filipino vessels near the Second Thomas Shoal and Scarborough Shoal.
- Militarization: China has converted reefs into artificial islands, equipping them with airstrips, radar, and missile systems.
- Mini-lateralism: Growth of the SQUAD (US-Japan-Australia-Philippines) to counter Chinese dominance.
Legal Aspects and UNCLOS
The United Nations Convention on the Law of the Sea (UNCLOS) defines the rights and responsibilities of nations regarding the use of oceans.
- 2016 PCA Ruling: The Permanent Court of Arbitration (The Hague) ruled in favor of the Philippines, stating China’s Nine-Dash Line has no legal basis.
- China’s Response: Beijing rejected the ruling as “null and void,” highlighting the lack of an enforcement mechanism in international law.
Impact on Global Stability
- Indo-Pacific Security: The dispute threatens the Free and Open Indo-Pacific (FOIP) concept.
- Arms Race: Increased military spending by ASEAN nations and frequent US-China naval face-offs raise the risk of unintended escalation.
India’s Interests and Role
India’s stance has evolved from “Look East” to “Act East”:
- Economic Stakes: Nearly 55% of India’s trade with the Indo-Pacific passes through the SCS.
- Energy Security: ONGC Videsh has oil exploration projects in Vietnam’s EEZ, which China frequently protests.
- Strategic Role: India supports UNCLOS and has increased naval cooperation with the Philippines (e.g., BrahMos missile deal) and Vietnam.
Challenges and Risks
- ASEAN Centrality: Internal divisions within ASEAN (e.g., Cambodia/Laos being pro-China) prevent a unified stance.
- Grey Zone Tactics: China uses fishing militias and “swarming” tactics that fall just below the threshold of open warfare.
Way Forward
- Binding Code of Conduct: Transitioning the 2002 Declaration into a legally binding Code of Conduct (CoC).
- Multilateralism: Strengthening forums like the Quad and ASEAN Outlook on the Indo-Pacific (AOIP).
- Legal Compliance: Encouraging all parties to respect the 2016 Arbitral Award.
Conclusion
The South China Sea Dispute is not merely a regional territorial row but a test for the global rules-based order. For India, a stable and open SCS is indispensable for its maritime security and economic aspirations.

(d) Though International Court of Justice declared them as no man's land, some South-East Asian countries claim them.
Answer: (b) China and Japan engage in maritime disputes over these islands in East China Sea
Explanation:
The Senkaku Islands, known as Diaoyu in China, are located in the East China Sea and are a major point of maritime dispute between China and Japan. They are not artificial islands in the South China Sea, nor have they been declared no man’s land by the International Court of Justice. This issue reflects the wider pattern of strategic maritime competition involving China in East Asia.

Q: With reference to the 'Nine-Dash Line', consider the following statements:
1. It was originally an eleven-dash line proposed in 1947.
2. The 2016 Permanent Court of Arbitration (PCA) ruling upheld its legal validity under UNCLOS.
