BEIJING — China’s coast guard said Sunday it took action against a Philippine vessel that ignored warnings and caused a light collision with its vessel in the disputed South China Sea, where confrontations between the two sides have increased.

Gan Yu, the coast guard spokesperson, said in a statement that the Philippine vessel entered the waters around Sabina Shoal in the Spratly Islands, known in Chinese as Xianbin Reef in the Nansha Islands. Gan said the Philippine ship ignored the Chinese warning and sailed toward the coast guard ship “unprofessionally” and “dangerously,” causing the two vessels to brush against each other. He said the Philippine vessel also had journalists on board to take pictures to “distort facts.”

“The responsibility is totally on the Philippines’ side. We sternly warn that the Philippine side must immediately stop the infringement and provocation, otherwise it must bear all consequences,” he said. Gan did not elaborate on what control measures the Chinese coast guard took.

The Bureau of Fisheries and Aquatic Resources in the Philippines said its vessel encountered aggressive and dangerous maneuvers from eight Chinese maritime vessels. It said the actions from the Chinese side were aimed at obstructing its vessel’s humanitarian mission to resupply Filipino fishermen with diesel, food and medical supplies.

China is rapidly expanding its military and has become increasingly assertive in pursuing its territorial claims in the South China Sea, which Beijing claims virtually in its entirety. The tensions have led to more frequent confrontations, primarily with the Philippines, though the longtime territorial disputes also involve other claimants including Vietnam, Taiwan, Malaysia and Brunei.

The latest incident came days after Chinese and Philippine coast guard ships collided near Sabina Shoal, a disputed atoll. At least two vessels were reported to be damaged in Monday’s collision but there were no reports of injuries.

Sabina Shoal lies about 140 kilometers (85 miles) west of the Philippine province of Palawan, in the internationally recognized exclusive economic zone of the Philippines.

The atoll is near Second Thomas Shoal, another flashpoint where China has hampered the resupply of Philippine forces. China and the Philippines reached an agreement last month to prevent further confrontations at Second Thomas Shoal.
