US Says China’s Scarborough Shoal Claim ‘Destabilizing’ Region
The US State Department publicly rejected China's declaration of a "national nature reserve" at Scarborough Shoal, calling it a "dubious" pretext, backed by coercion, to advance sweeping maritime claims in the South China Sea.
Chinese coast guard vessels have reportedly used water cannons against Filipino fishing boats and restricted their entry into the shoal's traditional fishing grounds in recent weeks.
The statement reaffirmed US support for the Philippines, a treaty ally, in the context of a free and open Indo-Pacific.
Both China and the Philippines continue to assert competing sovereignty claims over the shoal, which lies roughly 240 km from Luzon (Philippines) and far from mainland China.
South China Sea Dispute and the Nine-Dash Line
The South China Sea dispute involves overlapping sovereignty and maritime-zone claims by China, the Philippines, Vietnam, Malaysia, Brunei, and Taiwan over islands, reefs, and shoals in the sea. China bases its claim on the "nine-dash line," a boundary appearing on Chinese maps that covers roughly 90% of the sea, including areas far from its coast and well within the Exclusive Economic Zones (EEZ) of neighbouring states as defined by the UN Convention on the Law of the Sea (UNCLOS), 1982.
Key Details
- UNCLOS (1982) grants coastal states a 12-nautical-mile territorial sea and a 200-nautical-mile EEZ from baselines, within which they have sovereign rights over resources.
- In the 2013 case brought by the Philippines, the Permanent Court of Arbitration (PCA) at The Hague, constituted under UNCLOS Annex VII, ruled on 12 July 2016 that China's nine-dash line and "historic rights" claim have no legal basis under UNCLOS.
- China rejected the ruling as "null and void" and has not complied with it; it also refused to participate in the arbitration proceedings.
- Scarborough Shoal was seized by China from Philippine control in 2012 following a standoff and has since been under de facto Chinese control despite the 2016 ruling favouring Manila.
China's declaration of a "nature reserve" at Scarborough Shoal is viewed by the US and Philippines as a new legal-administrative tactic to entrench control over territory that the 2016 PCA award found China has no lawful claim to, continuing a pattern of using domestic legal instruments (fishing bans, marine reserves, coast guard law) to assert control in disputed waters.
India's Stakes in the South China Sea (UNCLOS Freedom of Navigation)
India does not have territorial claims in the South China Sea but has consistently called for freedom of navigation and overflight and adherence to UNCLOS, given its own reliance on these sea lanes for trade with East and Southeast Asia and its ONGC Videsh oil exploration blocks off the Vietnamese coast (within Vietnam's EEZ, contested by China).
Key Details
- India is a party to UNCLOS (ratified 1995) and has repeatedly urged that disputes be resolved as per international law, particularly UNCLOS.
- The South China Sea carries an estimated $3 trillion plus in annual trade, a share of which is India-bound.
- India's "Act East Policy" and defence partnerships with Vietnam, the Philippines, and Japan intersect with the freedom-of-navigation issue.
Renewed US-China friction over Scarborough Shoal underscores the strategic stakes for India in the wider Indo-Pacific, an area central to the Quad (India, US, Japan, Australia) and India's maritime security calculus.
- Scarborough Shoal lies about 240 km (124 nautical miles) from Luzon, Philippines, well within the Philippines' 200-nautical-mile EEZ under UNCLOS.
- The PCA ruling on the South China Sea arbitration case (Philippines v. China) was delivered on 12 July 2016.
- China's "nine-dash line" claims cover an estimated 90% of the South China Sea.
- Over $3 trillion worth of goods transit the South China Sea annually, making it one of the world's busiest maritime trade corridors.
