Rubio says US committed to Philippines in call about China's 'dangerous' actions

New U.S. Secretary of State Marco Rubio discussed China's "dangerous and destabilizing actions in the South China Sea" with his Philippine counterpart on Wednesday and underscored the "ironclad" U.S. defense commitment to Manila.

"Secretary Rubio conveyed that (China's) behavior undermines regional peace and stability and is inconsistent with international law," the U.S. State Department said in a statement on his call with Foreign Minister Enrique Manalo.

The Philippines has been embroiled in wrangles at sea with China in the past two years and the two countries have faced off regularly around disputed features in the South China Sea that fall inside Manila's exclusive economic zone.

Rubio's call followed his hosting of counterparts from Australia, India and Japan in the China-focused "Quad" forum on Tuesday, the day after President Donald Trump returned to the White House. The four recommitted to working together.

Quad members and the Philippines share concerns about China's growing power and analysts said Tuesday's meeting was designed to signal continuity in the Indo-Pacific and that countering Beijing will be a top priority for Trump.

In the call with Manalo, Rubio "underscored the United States’ ironclad commitments to the Philippines" under their Mutual Defense Treaty and discussed ways to advance security cooperation, expand economic ties and deepen regional cooperation, the statement said.

Just ahead of Trump's swearing-in, the Philippines and the United States carried out their fifth set of joint maritime exercises in the South China Sea since launching the joint activities in 2023.

Security engagements between the allies have soared under Philippine President Ferdinand Marcos Jr., who has pivoted closer to Washington and allowed the expansion of military bases that American forces can access, including facilities facing the Chinese-claimed but democratically-governed island of Taiwan.

Visiting the Philippines last week, Japanese Foreign Minister Takeshi Iwaya said a trilateral initiative to boost cooperation launched by Japan, the U.S. and the Philippines at a summit last year would be strengthened when the new U.S. administration took over in Washington.
