The United States has fully rejected China’s establishment of a national nature reserve on Scarborough Reef, citing threats to the Philippines’ traditional fishing grounds and alleging violation of the 2016 arbitration ruling. The move underscores heightened US‑China tensions in the South China Sea.

Key Takeaways

  • The US rejects China’s national nature reserve on Scarborough Reef.
  • It aims to protect the Philippines’ traditional fishing areas.
  • The action is framed as a breach of the 2016 arbitration decision.

Historical Background

In 2016, the Permanent Court of Arbitration ruled that China has no legal basis to claim resources within the Philippines’ Exclusive Economic Zone (EEZ) in the South China Sea. China dismissed the ruling, fueling ongoing disputes.

Current Developments

China approved the reef’s nature reserve in September 2025 and issued a 16‑article management regime in August 2024. The US State Department labeled the move “unilateral and illegal,” warning it would restrict Filipino fishermen’s access.

Why This Matters

BozokMedia analysis shows that the US rejection reinforces its commitment to a free and open Indo‑Pacific, signaling heightened strategic competition with China over maritime sovereignty.

"Washington’s stance sends a clear message that international maritime law will not be ignored," says maritime law expert Dr. Emily Chen.
