Secretary of State Antony J. Blinken spoke today with Philippine Secretary of Foreign Affairs Teodoro Locsin, Jr. Secretary Blinken and Secretary Locsin reaffirmed that a strong U.S.-Philippine Alliance is vital to a free and open Indo-Pacific region. Secretary Blinken stressed the importance of the Mutual Defense Treaty for the security of both nations, and its clear application to armed attacks against the Philippine armed forces, public vessels, or aircraft in the Pacific, which includes the South China Sea. Secretary Blinken also underscored that the United States rejects China’s maritime claims in the South China Sea to the extent they exceed the maritime zones that China is permitted to claim under international law as reflected in the 1982 Law of the Sea Convention. Secretary Blinken pledged to stand with Southeast Asian claimants in the face of PRC pressure. The two secretaries committed to continue building upon a relationship founded on shared strategic interests and history, democratic values, and strong people-to-people ties.
