What It Does

S.Res. 409 commemorates the 74th anniversary of the 1951 Mutual Defense Treaty (MDT) with the Philippines and lays out the Senate’s stance amid recent maritime run‑ins with China. It condemns Beijing’s coercive behavior, supports deeper U.S.–Philippine security cooperation, and reiterates that the MDT covers armed attacks on Philippine forces, public vessels, and aircraft—including the Coast Guard—anywhere in the South China Sea. In short: it’s a statement of support and deterrence, not a change to U.S. law.

Why It Matters

Tensions around features like Second Thomas and Scarborough Shoals have spiked, including close air and maritime encounters and injuries to Filipino personnel. The resolution aligns the Senate with the 2016 international tribunal ruling that rejected China’s expansive “nine‑dash line” claims and signals backing for Manila as incidents continue.

Who’s Against It

What’s Next

On October 22, 2025, the Senate Foreign Relations Committee approved S.Res. 409, sending it toward possible floor consideration. Because it’s a simple Senate resolution, if adopted it expresses the Senate’s position and does not go to the House or the President or carry the force of law.
