China's coast guard said the Philippines on Friday sent a civilian vessel to deliver provisions to its warship "illegally grounded" at Second Thomas Shoal, a disputed atoll in the South China Sea. The coast guard "questioned" and "monitored" the Philippine vessel throughout its supply mission,

The Philippines won a landmark case at the Permanent Court of Arbitration in 2016 that found China's sweeping claim of sovereignty in the South China Sea had no basis under international law. It now wants to hold Beijing accountable for what it says is its harvesting of giant clams and substantial environmental damage to coral reefs in the Philippines' exclusive economic zone.
