Ten years after the South China Sea arbitral ruling that China rejects, the Philippines is accelerating naval modernisation

Summary

The Philippines marked a decade since the Permanent Court of Arbitration ruled in July 2016 that China's nine-dash-line claims had no legal basis under international law, a ruling China has refused to recognise. Ten years on, Manila is accelerating naval modernisation with new fleet acquisitions, relying on the legal architecture of the ruling to justify allied partnerships and coast-guard operations. Foreign Policy assessed that while the ruling did not change China's behaviour on the water, it gave Manila a basis for rallying US, Japanese, Australian and New Zealand support. The South China Morning Post reported a rare China-Philippines naval standoff near Scarborough Shoal in recent weeks, a Chinese-controlled reef that the Philippines also claims.

The split

Asian Military Review and Foreign Policy, both from outside China, agreed the ruling shifted the diplomatic terrain in Manila's favour but acknowledged China's physical control of most disputed features has not changed. Chinese state media was not in this feed's coverage. The SCMP framing, from Hong Kong, noted the standoff near Scarborough Shoal in a factual register, reflecting the city's editorial caution around China coverage.

By the numbers

• 10, years since the Permanent Court of Arbitration issued its ruling in July 2016
• 0, times China has recognised or complied with the ruling
• Multiple, naval assets and coast-guard vessels Philippines has added since 2016 under its modernisation programme

Why it matters

The ruling's tenth anniversary coincides with the Philippines making the clearest pivot toward military self-reliance in a generation. If China continues to reject international law as a constraint in the South China Sea, the ruling's durability depends entirely on the coalition Manila can maintain, particularly with the United States under a shifting foreign-policy posture.

What to watch

• Whether the Scarborough Shoal standoff escalates to a formal incident or de-escalates
• Progress on Philippines naval acquisitions and whether new vessels change the balance at contested features
• How China responds to the 10th-anniversary commemoration diplomatically
• Whether ASEAN takes any collective position on the anniversary or the standoff
