The US secretary of state opens his term by reaffirming Washington’s commitment to the Philippines and other regional allies.

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.

The Philippines alleges Chinese activities, including dredging, coral harvesting, and the construction of artificial islands, have caused significant and irreversible damage to coral reefs and marine biodiversity. China has accused the Philippines of causing damage to the Second Thomas Shoal by intentionally grounding a warship there in 1999.

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.

Beijing and Manila have agreed to continue talks on settling their territorial differences despite Philippine protests about the presence of a Chinese "monster ship" near the contested Scarborough Shoal.

The Philippines and China agreed to seek common ground and find ways to cooperate despite their disagreements in the South China Sea, their foreign ministries said on Thursday, as heated rows persist over vessels deployed around disputed features.

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