Indonesia and the Philippines: Strengthening Maritime Security and Diplomatic Ties
Indonesia and the Philippines share a deep-rooted relationship built on kinship and a shared geography as two of Southeast Asia’s largest archipelagic nations. From their roles as founding members of ASEAN to their current efforts to secure volatile waterways, these two allies are intensifying their cooperation to maintain regional stability and economic growth.
A Foundation of Diplomatic Kinship
The diplomatic bond between Indonesia and the Philippines isn’t recent. The two nations established formal diplomatic relations on November 24, 1949. Over the decades, this relationship has evolved into one of the most critical bilateral partnerships within the Association of Southeast Asian Nations (ASEAN). To maintain this connection, both countries operate embassies in their respective capitals—Jakarta and Manila—and maintain consulates in Davao City (Indonesia) and Manado (Philippines).
This partnership is further solidified by their shared membership in several international organizations, including:
- ASEAN: Both were among the five founding members who signed the Bangkok Declaration on August 8, 1967.
- APEC: Collaborating on Asia-Pacific economic cooperation.
- Non-Aligned Movement: Maintaining strategic independence in global politics.
- BIMP-EAGA: Working alongside Brunei Darussalam and Malaysia in the East ASEAN Growth Triangle to boost sub-regional development.
Securing the Seas: Joint Patrols and Defense
Maritime security is currently a top priority for both nations. Because both countries are composed mostly of islands, they face similar challenges regarding territorial integrity and piracy. To combat these risks, the Philippines and Indonesia are enhancing joint maritime patrols in the Sulu and Celebes seas.

Beyond tactical patrols, the two nations align on broader geopolitical issues. Most notably, both Indonesia and the Philippines reject the territorial claims of the People’s Republic of China in the region. This shared stance underscores their commitment to a rules-based maritime order and the security of their sovereign waters.
Recent Diplomatic Milestones and Future Outlook
High-level state visits continue to drive the bilateral agenda. A significant recent event occurred on October 20, 2024, when Philippine President Bongbong Marcos and First Lady Liza Araneta Marcos attended the inauguration dinner of Indonesian President Prabowo Subianto. Such visits reinforce the political will to strengthen defense cooperation and logistics ties between the two militaries.
Looking ahead, the Philippines is preparing for the ASEAN Chairship in 2026. This upcoming leadership role provides a strategic opportunity for the Philippines to push a shared maritime agenda and foster greater ASEAN unity to navigate complex sea risks.
