Marcos Advocates for UNCLOS and Regional Stability at ASEAN Summit

Philippine President Champions International Law and Collaborative Security

At the recent ASEAN Summit, philippine President Ferdinand Marcos Jr. strongly advocated for the adherence to the United Nations Convention on the Law of the sea (UNCLOS) and emphasized its crucial role in maintaining regional stability within the South China Sea. This stance underscores the Philippines’ commitment to a rules-based international order and peaceful dispute resolution. The summit, a key platform for Southeast Asian cooperation, saw Marcos actively engaging wiht regional leaders on issues of maritime security, economic partnerships, and geopolitical challenges.

UNCLOS: The cornerstone of Maritime Rights

President Marcos consistently highlighted UNCLOS as the definitive legal framework governing all activities in the oceans and seas. He stressed that all claimant states in the South China Sea shoudl respect the convention’s provisions, particularly regarding:

* exclusive economic Zones (EEZs): The right of a coastal state to exploit resources within 200 nautical miles of its coastline.

* Continental Shelf Rights: Extending the EEZ to include the seabed and subsoil beyond 200 nautical miles under specific geological conditions.

* Freedom of Navigation: Ensuring unimpeded passage for all vessels in international waters.

* Peaceful Dispute Resolution: Utilizing mechanisms like arbitration and the International Tribunal for the Law of the Sea (ITLOS) to settle disagreements.

The Philippines’ position is rooted in the 2016 Permanent Court of Arbitration ruling, which invalidated China’s expansive “nine-dash line” claim in the South China Sea. Marcos reiterated the importance of upholding this ruling, a key element in maritime dispute resolution.

Regional Security Concerns and ASEAN Centrality

Beyond UNCLOS, Marcos addressed broader regional security concerns, including:

* Increased Militarization: Expressing concern over the growing military presence in the South China Sea and its potential to escalate tensions.

* Coercive Activities: Condemning actions that intimidate or coerce other claimant states, such as harassment of fishermen and interference with resource exploration.

* Cybersecurity Threats: Recognizing the emerging challenges posed by cyberattacks and disinformation campaigns that can destabilize the region.

he championed ASEAN centrality in addressing these challenges, advocating for the organization to play a leading role in fostering dialog, building trust, and promoting cooperation. This includes strengthening the ASEAN-China Dialogue and exploring opportunities for joint initiatives on maritime security and environmental protection. The concept of regional security architecture was frequently referenced during discussions.

Bilateral Engagements and Strategic Partnerships

during the summit, President Marcos engaged in several bilateral meetings with key regional leaders, including those from the United States, Japan, Australia, and Indonesia. These discussions focused on strengthening strategic partnerships and exploring avenues for enhanced cooperation in areas such as:

  1. Defense and Security: Joint military exercises, intelligence sharing, and capacity building.
  2. economic Cooperation: Promoting trade and investment, enhancing supply chain resilience, and fostering digital conversion.
  3. Climate Change: Collaborating on climate mitigation and adaptation efforts, including renewable energy development and disaster risk reduction.

These partnerships are seen as vital for bolstering the Philippines’ defense capabilities and promoting a balanced approach to regional security. The strengthening of the US-Philippines alliance was a particularly prominent theme.

The South China Sea Code of Conduct Negotiations

A significant portion of the summit discussions revolved around the ongoing negotiations for a Code of conduct (COC) in the South China Sea. President Marcos urged all parties to accelerate the negotiations and ensure that the COC is:

* Effective: Providing clear guidelines for behavior and mechanisms for dispute resolution.

* Substantive: Addressing key issues such as the prevention of incidents at sea and the protection of fishermen’s rights.

* Consistent with UNCLOS: Upholding the principles of international law and ensuring that the COC does not undermine the rights of claimant states.

He emphasized the need for a COC that is legally binding and enforceable, rather than a mere declaration of intentions. The progress of the COC negotiations remains a critical indicator of the region’s commitment to peaceful resolution.

Economic Implications and the Blue Economy

Marcos also highlighted the economic opportunities presented by a stable and secure South China Sea. He advocated for the development of a blue economy – a enduring use of ocean resources for economic growth – and emphasized the importance of protecting marine biodiversity. This includes promoting sustainable fisheries, developing marine tourism, and investing in renewable energy sources such as offshore wind power. Sustainable development in the region is intrinsically linked to maritime security.

Case Study: The Scarborough Shoal Dispute

The situation surrounding Scarborough Shoal (Panatag Shoal) remains a key point of contention. The Philippines continues to assert its sovereign rights over the shoal, which is located within its EEZ. incidents involving Chinese Coast Guard harassment of Filipino fishermen have repeatedly underscored the need for a clear and enforceable COC. This ongoing dispute serves as a stark reminder of the challenges facing the region and the importance of upholding international law.
