President Ferdinand Marcos Jr. is set to reiterate the need for a rules-based international order in the South China Sea at the  Association of Southeast Asian Nations, amid increasing tensions between the Philippine and Chinese coast guards in the West Philippine Sea.

Marcos made this remark as he left Manila on Monday bound for Jakarta, Indonesia, to attend the 43rd ASEAN Summit and Related Summits.

Marcos said he will also bring up issues on strengthening food security, calling for climate justice, tapping the potential of the digital and creative economies, protecting migrant workers in crisis situations as well as combatting human trafficking in the region.

"Once again, I will use his opportunity to advance Philippine priorities in ASEAN and work with our other ASEAN member states not only in addressing the complex challenges facing the region but also in pursuing opportunities for ASEAN as an epicenter of growth," Marcos said.

Marcos said there will be discussions covering developments in the South China Sea, the situation in Myanmar and the conflict in Ukraine during the ASEAN Plus 3 and East Asia Summits.

"I will also take the opportunity to meet the bilateral partners at the sidelines of the SEAN summit to advance cooperation that will benefit our national priorities," he said.

Marcos said his administration would continue to ensure that the Philippines'  "constructive engagements with ASEAN, dialogue partners and stakeholders" will serve the national interest of the country and the well-being of the Filipino people.
