MANILA, (PIA) -- The Philippines on Wednesday rejected China's assertion that its recent joint air patrol with the United States in the disputed South China Sea constituted "stirring up trouble," asserting its right to conduct such activities within its own territory.

National Security Adviser Eduardo Año said the February 21 exercise between the Philippine Air Force (PAF) and the U.S. Pacific Air Force (PACAF) was "lawful and routine," aimed at bolstering cooperation and regional security.

"Our engagements with the United States are well within our rights as a sovereign and independent nation, aimed at enhancing maritime security, promoting regional stability and upholding international law," Año said in a statement. "We reject any assertion from other countries that seeks to undermine our legal and legitimate activities."

Earlier, China's Southern Theater Command criticized the joint patrol, calling it "provocative" and accusing the Philippines of "enlisting external forces" to stir up trouble.

However, Año countered that the joint patrol occurred entirely within Philippine territorial waters, as recognized by the United Nations Convention on the Law of the Sea (UNCLOS). He urged China to respect the Philippines' sovereign rights and adhere to international legal frameworks.

"Adhering to established legal frameworks is crucial for fostering peaceful relations, stability, and cooperation between the Philippines and China," Año emphasized. "Respecting and following international law is essential for maintaining peace, resolving disputes, and advancing our shared interests in the region."

The joint patrol comes amid heightened tensions in the South China Sea, where China claims vast swathes of territory despite competing claims from several Southeast Asian nations, including the Philippines. The Philippines has recently strengthened its defense ties with the U.S., conducting more joint exercises and seeking increased military assistance.

Año reiterated the Philippines' commitment to a rules-based order in the region and its intention to continue collaborating with partners to ensure regional security and prosperity. (JCO/PIA-NCR)
