The two countries have had numerous run-ins in areas of the South China Sea in recent months, especially the disputed Second Thomas Shoal, part of the Spratly Islands.
The Pentagon said in May it would protect the Philippines if its coast guard came under attack "anywhere in the South China Sea".
Beijing claims sovereignty over almost the entire South China Sea, including parts of the exclusive economic zones of the Philippines, Vietnam, Malaysia, Brunei and Indonesia.
"The provocative, irresponsible, and illegal action" of the Chinese coast guard vessel "imperilled the safety of the crew" of the Philippine boat, the task force said.
"The Philippines behaviour seriously violates the international rules on avoiding collisions at sea and threatens the navigation safety of our vessels," the coast guard said.
