WASHINGTON (AP) — The Biden administration on Friday reassured the Philippines anew that the U.S. commitment to the country’s defense is steadfast amid increasing concerns about provocative Chinese actions in disputed areas of the South China Sea.

A day after President Joe Biden convened a trilateral summit involving himself, Japanese Prime Minister Fumio Kishida and Philippine President Ferdinand Marcos Jr., the U.S. and Filipino foreign and defense ministers and national security advisers met to discuss strategic and military issues.

Secretary of State Antony Blinken, Defense Secretary Lloyd Austin and national security adviser Jake Sullivan hosted their Philippine counterparts at the State Department.

“Today’s meeting reflects the growing and deepening cooperation between our countries on a broad array of issues and of course our shared commitment to a free and open Indo-Pacific, including in the South China Sea,” Blinken said in brief opening remarks. “We very much welcome this opportunity to pursue that cooperation, that collaboration and of course we stand with the Philippines in our iron-clad defense commitments including the Mutual Defense Treaty.”
