South China Sea has assumed great geopolitical significance in the present context. Comment.
Approach · directive: “comment”
What it asks · Explain why the South China Sea matters (trade routes, resources, territorial claims, great-power rivalry) and what it means for India.
It asks 2 things — answer each
- Comment: why the South China Sea has assumed geopolitical significance (trade, resources, claims, law, great-power rivalry)
- Comment: what it means for India and the position India takes
Open with · The South China Sea joins the Indian and Pacific Oceans through the Malacca Strait; the 2016 arbitral award turned overlapping claims there into a test of law against power.
Cover
- Trade artery: sea lanes carrying a large share of world trade, including India's trade with East Asia.
- Resources: fisheries and believed oil and gas make exclusive economic zone rights worth contesting.
- Claims: China's nine-dash line overlaps claims of Vietnam, the Philippines, Malaysia, Brunei and Taiwan; artificial islands built on Spratly features.
- Law: Philippines v. China (12 July 2016) found no legal basis for China's historic rights; China rejected the award.
- Rivalry: US freedom-of-navigation operations versus Chinese assertiveness; a divided ASEAN lacks a binding Code of Conduct.
- India: sea-lane security, ONGC Videsh blocks off Vietnam, Act East Policy (since 2014), support for UNCLOS and freedom of navigation.
Close with · India gains most from an open, rules-based sea: backing ASEAN centrality and UNCLOS while deepening partnerships keeps these waters a commons, not one power's lake.

The South China Sea joins the Indian and Pacific Oceans through the Malacca Strait, and six claimants contest it. The July 2016 arbitral award made it a test of law against power.
Why its significance has grown
- Trade artery: a large share of world seaborne trade, including India's trade with East Asia, sails these sea lanes.
- Resources: rich fisheries and believed oil and gas reserves make exclusive economic zone rights worth contesting.
- Overlapping claims: China's 'nine-dash line' cuts across the claims of Vietnam, the Philippines, Malaysia, Brunei and Taiwan.
- Militarised reefs: China built artificial islands at seven Spratly features, which the tribunal found caused severe harm to coral reefs.
- Law versus power: in Philippines v. China (12 July 2016) the UNCLOS tribunal found no legal basis for China's historic rights within the nine-dash line; China rejected the award.
- Great-power rivalry: US freedom-of-navigation operations confront Chinese assertiveness, while a divided ASEAN has yet to agree a binding Code of Conduct.
South China Sea: sea lanes; fisheries and hydrocarbons; overlapping claims; UNCLOS award; US–China rivalry
What it means for India
- Sea-lane security: trade with ASEAN, Japan and Korea crosses these waters, so any blockade or clash raises cost and risk.
- Energy stake: ONGC Videsh explores blocks off Vietnam despite Chinese objections.
- Strategic space: the Act East Policy (since 2014) and defence ties with Vietnam widen India's role in the Indo-Pacific.
- Principle: India backs freedom of navigation and overflight and peaceful settlement under UNCLOS, without taking sides on sovereignty.
- Mirror for the Indian Ocean: if force can rewrite maritime rights in the east, India's own sea lanes and island territories face the same precedent.
India gains most from an open, rules-based sea: backing ASEAN centrality and UNCLOS while deepening partnerships keeps these waters a commons, not one power's lake.
