China conducted naval and air patrols around the Scarborough Shoal in the South China Sea on Saturday, the China Southern Theatre Command said.
The shoal is in the Philippines' exclusive economic zone, but China also claims it as part of its territory.
The Philippine embassy in Beijing did not immediately respond to a request for comment.
China has stepped up combat readiness patrols in the area in January, "resolutely countering the infringement provocations of individual countries within the region," the post said.
The militaries of the Philippines and the United States carried out joint exercises in the Scarborough Shoal area earlier in the week, in the 11th such drill since November 2023, Manila's armed forces said on Tuesday.
The joint sail showcased the Philippines' frigate Antonio Luna, a Philippine Coast Guard offshore patrol vessel, as well as two military planes and a helicopter. Meanwhile, the US Indo-Pacific Command deployed the USS John Finn, an Arleigh Burke-class guided missile destroyer and an MH-60R Seahawk helicopter.
