One must understand that Bajo de Masinloc, or Scarborough Shoal, is a strategic area that can extend PLA firepower. The Philippine government must have an initiative to respond to this situation.
The infographic below shows the potential of the area. @Drethegrater

During the operation, the Diego Silang (FFG7) monitored two Chinese vessels a few nautical miles away. These ships were identified as the CNS Qinzhou No. 555 from the PLA Navy and the CNS Cutter No. 5304 from the Chinese Coast Guard.
Reported by Bea Peniza of @ibcdigital13.
PDM Report: BRP Diego Silang (FFG-7) issued four radio challenges during a maritime patrol in the West Philippine Sea to CNS Qinzhou (555), the latest Type 054B-class frigates of the PLA Navy.
This marks the first time this particular class of frigates has been sighted.

Aside from the deployment of the MQ-9A drone, the U.S.–Philippines partnership continues to develop Basa Air Base’s infrastructure. Recent satellite imagery shows land-clearing activities reportedly linked to the expansion of the base’s tarmac facilities.

The deployment of all four frigates reflects the Philippine Navy’s efforts to rebuilt its maritime presence following the retirement of its Patrol Craft Escorts.
The addition of two more HDF-3200 frigates is expected to further boost operations. Set to be delivered by 2028.
Based on available information, all four Philippine Navy frigates are currently engaged in separate operations. With three operating within Philippine waters and one deployed overseas, their active status highlights the increasing operational demands across the country’s EEZ.

Isang dekada matapos manalo ng Pilipinas laban sa China sa 2016 Arbitral Ruling sa ilalim ng United Nations Convention on the Law of the Sea o UNCLOS, pinag-aaralan ang paghahain ng ikalawang arbitration case.
Ito’y matapos mamataan sa Bajo de Masinloc ang isang movable floating platform na pag-aari umano ng China. Bakit nga ba nababahala ang mga eksperto dahil dito? Alamin sa video.

The Type 054B-class multirole guided-missile frigates are the Navy's newest frigate model. It's rare to see them in the waters of the West Philippine Sea, which could suggest upcoming increases in the CCP's presence in the area.
