U.S. President Joe Biden on Sunday met virtually with his counterparts from Japan and the Philippines to advance cooperation among the three countries, the White House said.

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.
