The Philippine Department of Foreign Affairs has refuted China's claim that the Philippines agreed not to construct on the BRP Sierra Madre in Ayungin Shoal as part of a 2024 temporary understanding, asserting no permission-seeking was involved.

Malacañang announced that President Marcos condemned the China Coast Guard's baton attack on a Filipino sailor during the latest incident near BRP Sierra Madre, asserting that Filipino personnel acted within their mandate and rights.

Espionage activities uncovered by the Armed Forces of the Philippines (AFP) included gathering information about troops in the BRP Sierra Madre at Ayungin Shoal.
