Teodoro and Marles noted that 2026 marks the 10th anniversary of the landmark 2016 Arbitral Award under the United Nations Convention on the Law of the Sea (UNCLOS).
They underscored the importance of freedom of navigation, overflight and other lawful uses of the sea consistent with UNCLOS and reiterated that maritime disputes must be resolved peacefully in accordance with international law.

Separately, Teodoro defended Administrative Order 29, issued by then-President Benigno Aquino III in 2012, which institutionalized the use of the term “West Philippine Sea” for the country’s maritime areas on its western seaboard.
He said government officials who disagree with the policy should seek its nullification before the Supreme Court instead of refusing to recognize it while remaining in government.
The Defense chief was responding to criticism, including from Vice President Sara Duterte, who challenged him to identify officials he had previously described as “pro-China.”
Teodoro clarified that his earlier remarks referred to officials who not only oppose Administrative Order 29 but also refuse to recognize it despite being bound by their oath to implement existing government policies unless these are struck down by the courts.
“The standard is simple: who not only opposes Administrative Order 29, but also refuses to recognize it — both elements being necessary, especially in light of our recent filing of nautical charts for Bajo de Masinloc and Panatag,” he said.
Teodoro added that the DND does not brand Filipinos based on beliefs or opinions.

“In the same way that red-tagging and other ad hoc practices are not employed by this organization, tagging Filipinos based on belief rather than covert or overt acts is not done by the Defense Department,” he said.
The Philippines and China have figured in a series of increasingly tense confrontations in the WPS over the past years.
China Coast Guard and Chinese maritime militia vessels have used water cannons, dangerous blocking maneuvers and collisions against Philippine resupply and patrol missions, particularly near Ayungin Shoal and Bajo de Masinloc.
The 2016 Arbitral Award invalidated China’s expansive “nine-dash line” claim and affirmed that maritime features within the Philippines’ exclusive economic zone do not generate maritime entitlements for Beijing.
Although the ruling is legally binding under UNCLOS, China has consistently rejected it, while the Philippines continues to invoke it as the legal basis for asserting its sovereign rights in the West Philippine Sea.
