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.

US Secretary of State Marco Rubio reaffirmed Washington's commitment to Manila and condemned Beijing for its "dangerous and destabilising" actions in the Sea, in his first phone call with Philippine Foreign Secretary Enrique Manalo.

A Philippine security official says China is “pushing us to the wall” with growing aggression in the disputed South China Sea and warned that “all options are on the table” for Manila’s response, including new international lawsuits.

The Philippines won a landmark case at the Permanent Court of Arbitration in 2016 that found China's sweeping claim of sovereignty in the South China Sea had no basis under international law. It now wants to hold Beijing accountable for what it says is its harvesting of giant clams and substantial environmental damage to coral reefs in the Philippines' exclusive economic zone.

Secretary of State Marco Rubio said the US remained committed to the Philippines' defense as tensions simmer with Beijing in the South China Sea.
