THE Philippines appeared to be conducting a resupply mission over the weekend for its military outpost aboard the BRP Sierra Madre at Second Thomas Shoal, according to monitoring by the maritime transparency initiative SeaLight.
The Philippine Coast Guard (PCG) has deployed the 44-meter BRP Malabrigo and the 97-meter BRP Teresa Magbanua in support of the operation, with the latter having previously been the longest-deployed PCG asset in the West Philippine Sea.
As usual, the PCG support vessels are being closely shadowed by China Coast Guard (CCG) and maritime militia ships in the disputed waters.
The mission comes just weeks after a violent clash on July 20, 2026, near the shoal — known as Ayungin Shoal in the Philippines and Ren’ai Jiao in China — during which Chinese coast guard personnel allegedly boarded Philippine boats and injured a Filipino Navy sailor with a metal rod. The sailor was subsequently medically evacuated.
China released video footage accusing Philippine personnel of ramming a CCG vessel and attacking its officers with paddles and long poles, claims that Manila has rejected.
Beijing has maintained that its law enforcement activities in the waters near Ayungin Shoal are “lawful and legitimate.”
The resupply attempt today follows a significant escalation of tensions at the shoal, which has become one of the region’s most volatile flashpoints due to competing claims.
The Philippines maintains a small military presence on the BRP Sierra Madre, a World War II-era warship deliberately grounded in 1999 to serve as an outpost.
President Ferdinand Marcos Jr. recently confirmed for the first time a “provisional understanding” with Beijing over resupply missions to the outpost, although he insisted this did not mean Manila was seeking China’s permission or surrendering sovereignty.
He characterized such notifications as “standard practice” to prevent miscalculation.
Following last month’s incident, the Armed Forces of the Philippines (AFP) monitored a significant Chinese presence in the area, with seven China Coast Guard vessels and two People’s Liberation Army-Navy warships observed near Ayungin Shoal.
The Philippines has consistently rejected China’s claims in the South China Sea, citing the 2016 international arbitral ruling that upheld Manila’s maritime rights. Beijing does not recognize the ruling.
Also on Saturday, the Chinese Embassy accused Defense Secretary Gilbert Teodoro of “falsification and defamation” and distorting facts regarding the arrest of Chinese nationals during a law enforcement raid at a steel manufacturing plant.
This was in relation to the raid on Davao Mighty Steel Corp., where 14 people — including 10 Chinese and four Filipinos — were arrested and 174 Filipino workers were rescued after being exposed to hazardous conditions.
On a Facebook post, Teodoro said that a Filipino worker in the steel plant suffered severe burns amid reported deficiencies in personal protective equipment and safety procedures.
The Chinese Embassy rejected Teodoro’s claims, asserting that the defense secretary’s claims are unfounded and distorting the reality of the ongoing legal cases.
