WASHINGTON/BEIJING – The United States said on Oct 13 it stood by its Philippine ally and emphasised their mutual defence treaty after vessels from China and the Philippines clashed amid heightened tensions in the disputed South China Sea.

Earlier, China's Foreign Ministry urged Manila not to challenge Beijing's efforts to "safeguard its territorial sovereignty and maritime rights and interests" after the Oct 12 incident in the Spratly Islands, in which the Philippines said

US State Department spokesman Tommy Pigott condemned China's "ramming and water cannoning" of a Philippines vessel and said Washington stood with its ally “as they confront China's dangerous actions which undermine regional stability”.

In a statement, Mr Pigott reaffirmed that Article IV of the 1951 US Philippines Mutual Defence Treaty "extends to armed attacks on Philippine armed forces, public vessels, or aircraft – including those of its Coast Guard – anywhere in the South China Sea".

China and the Philippines have traded accusations over the confrontation near Sandy Cay, a coral reef within the Spratly Islands.

The two nations have confronted each other repeatedly in recent years in the South China Sea, a strategic trade route that facilitates more than US$3 trillion (S$3.9 trillion) in annual ship-borne commerce, and which China claims most of.

Tensions have heightened recently and Mr Lin Jian, a spokesman for China's Foreign Ministry, told a regular press briefing that the Philippines should immediately stop "violations and provocations".

The US State Department said: "China's sweeping territorial and maritime claims in the South China Sea and its increasingly coercive actions to advance them at the expense of its neighbours continue to undermine regional stability and fly in the face of its prior commitments to resolve disputes peacefully."

In 2024, during the former Biden administration, two senior Republican US senators called for a list of options developed by the Pentagon and State Department to support the Philippines against Beijing in the South China Sea, saying that limiting responses to verbal assurances of the applicability of Article IV undermines the credibility and value of these commitments.
