Key Security Developments

• Expanded US-Philippines Military Cooperation for 2026
  On September 5, 2026, the United States and the Philippines finalized plans for over 500 joint military activities for the year 2026 during the annual Mutual Defense Board-Security Engagement Board (MDB-SEB) meeting in Camp Smith, Hawaii. This ambitious plan, approved through the "8-Star Memo," represents the most extensive slate of joint engagements to date, including large-scale exercises like Balikatan 2026 and numerous smaller training events. The increased cooperation aims to bolster deterrence, enhance disaster response capabilities, and reinforce regional stability under the 1951 Mutual Defense Treaty, with a key focus on Maritime Cooperative Activities (MCAs) to safeguard freedom of navigation in contested waters.

• Senate Committee Approves Philippines-France Visiting Forces Agreement
  The Philippine Senate Committee on Foreign Relations approved the Status of Visiting Forces Agreement (SOVFA) between the Philippines and France on September 11, 2026, moving it closer to plenary ratification. This landmark agreement will make France the first European nation to have a SOVFA with the Philippines and the country's sixth active visiting forces pact. Defense Secretary Gilberto Teodoro Jr. emphasized that the pact would enhance defense cooperation, joint training, and strategic collaboration, citing France's support for the 2016 Arbitral Ruling and freedom of navigation in the Indo-Pacific.

• Exercise Salaknib 2026 Commences
  Exercise Salaknib 2026 officially commenced with a formal opening ceremony, reaffirming the enduring partnership between the United States Army and the Armed Forces of the Philippines. Thousands of US and Philippine soldiers are participating in complex, multi-domain training events, including jungle warfare, aviation operations, advanced live-fire drills, and comprehensive archipelagic defense concepts. This annual exercise is designed to enhance combat readiness and interoperability, sharpening collective skills to uphold a free and open Indo-Pacific.

• Philippines to Co-Host ASEAN-India Maritime Exercise 2026
  The Philippine Navy is set to participate in the ASEAN-India Maritime Exercise (AIME) 2026 from September 28 to October 2, 2026, with India and the Philippines serving as designated hosts. This multilateral exercise will involve navies from India and 10 ASEAN countries, aiming to improve regional maritime security and stability, strengthen partnerships, and enhance interoperability during maritime operations. Final preparations for AIME 2026 were synchronized during a planning conference held from August 10-12 in Pasay City.

• Defense Secretary Teodoro Confronts China at Seoul Defense Dialogue
  From September 7-9, 2026, Secretary of National Defense Gilberto C. Teodoro, Jr. represented the Philippines at the Seoul Defense Dialogue (SDD) 2026, where he publicly confronted China's coercive behavior in the South China Sea. Teodoro reaffirmed the Philippines' commitment to international law, including UNCLOS and the 2016 South China Sea Arbitral Award, and framed the Philippines' position as part of a broader regional concern rather than a bilateral dispute. He warned that any perceived gaps in deterrence, such as cuts to US-South Korea military drills, could be exploited by China.

• President Marcos Jr. Calls for Unity in Maritime Defense
  President Ferdinand R. Marcos Jr. called on Filipinos to unite in defending the country's maritime rights and protecting its waters during the observance of Maritime and Archipelagic Nation Awareness Month (MANA Mo) 2026 in September. His message emphasized the shared responsibility to uphold lawful rights and protect maritime patrimony, coinciding with the anniversary of the 2016 South China Sea Arbitral Award. The President urged greater public understanding and concrete measures to advance Philippine maritime rights and responsible stewardship of marine resources.

• Increased Defense Budget and Modernization Program Funding
  The proposed 2027 national budget, announced on September 5, 2026, includes a significant increase for the Armed Forces of the Philippines (AFP), with PHP316.71 billion earmarked for the AFP, a 6.85 percent increase over its 2026 budget. The Revised AFP Modernization Program is proposed to receive PHP50 billion, up from PHP40 billion in 2026, signaling a robust push for modernization. This funding aims to enhance military capabilities, with Horizon 3 of the modernization program focusing on territorial defense, including air defense and anti-ship missile systems.

• US to Deploy Coast Guard Cutters to the Philippines
  The United States announced it would send six fast-response Coast Guard cutters to the Philippines and Singapore in September 2026, previously based in the Middle East. Additionally, Washington plans to transfer two new Coast Guard vessels to the Philippines specifically for search-and-rescue operations and to enhance maritime domain awareness. This deployment is expected to significantly bolster the Philippines' maritime security capabilities in the South China Sea.

• Persistent, Declining Terrorist Threat
  According to the Global Terrorism Index (GTI) 2026 and the US Department of State's Country Reports on Terrorism 2024, the Philippines has made significant progress in countering terrorism, improving its GTI ranking to 23rd out of 163 countries. While no significant violent activities from known IS-affiliated terrorist groups were monitored for 2025 and mid-2026, threats persist from ISIS-linked remnants, foreign fighters in Mindanao, and private armed groups (PAGs). The Department of Justice Task Force on Anti-Terrorism secured three convictions against terrorists, and the Philippine National Police launched an anti-terrorism awareness campaign on September 5, 2026.

• Internal Political Instability with VP Sara Duterte
  An arrest warrant was issued against Vice President Sara Duterte on September 5, 2026, for alleged grave threats against President Ferdinand "Bongbong" Marcos Jr., First Lady Liza Araneta-Marcos, and former speaker Martin Romualdez. Vice President Duterte subsequently posted bail at a Quezon City court. This development has been noted as contributing to worsening instability in the Philippines.

Geopolitical Impact and Regional Dynamics

The Philippines' security developments this week underscore its assertive and diversified approach to navigating complex regional dynamics. The approval of the SOVFA with France and ongoing negotiations with the UK demonstrate a clear strategy to broaden its network of security partners beyond its traditional alliance with the United States. This move is particularly significant as it brings a major European power with Pacific territories and a commitment to freedom of navigation into closer defense cooperation with Manila, strengthening the international coalition supporting a rules-based order in the Indo-Pacific. This diversification aims to enhance the Philippines' strategic resilience and deterrence capabilities, especially in the face of persistent challenges in the South China Sea.

Relations with major powers continue to be a central theme. The finalization of over 500 joint military activities with the US for 2026 on September 5, 2026, reaffirms the "ironclad" nature of the US-Philippines alliance and sends a strong message of deterrence to China regarding potential aggression in the region. This robust engagement, coupled with the US deployment of Coast Guard cutters to the Philippines in September, significantly enhances Manila's maritime security and domain awareness capabilities. Simultaneously, Defense Secretary Teodoro's public condemnation of China's "rudeness, boorishness, abusiveness" and "wolf warrior diplomacy" at the Seoul Defense Dialogue highlights Manila's increasing willingness to directly challenge Beijing's narrative and actions in the West Philippine Sea.

The Philippines' participation in the upcoming ASEAN-India Maritime Exercise (AIME) 2026 further illustrates its commitment to multilateral security cooperation within the Indo-Pacific. President Marcos Jr.'s attendance at the BRICS Summit in New Delhi as an "outreach country" and his planned bilateral meeting with Indian Prime Minister Narendra Modi on September 12, 2026, signal a strategic effort to strengthen ties with emerging global powers, focusing on defense, trade, and digital cooperation. These diplomatic engagements reflect the Philippines' "principled, pragmatic, and clear-eyed" independent foreign policy, aiming to maximize national interest and avoid zero-sum choices amid intensifying geopolitical competition. The ongoing tensions in the South China Sea, characterized by China's "salami slicing" tactics and increased military and coast guard activities, remain the most critical regional flashpoint, driving much of the Philippines' defense and diplomatic strategies.

Military and Defense Analysis

The Armed Forces of the Philippines (AFP) is poised for a significant boost in its modernization program, with the proposed 2027 national budget allocating PHP316.71 billion for the AFP, a 6.85% increase over the 2026 budget. A substantial PHP50 billion is earmarked for the Revised AFP Modernization Program, an increase from PHP40 billion in 2026, signaling a robust commitment to enhancing military capabilities. This funding is crucial as the AFP transitions to Horizon 3 of its modernization, which focuses on developing a stronger, multi-domain force with real deterrence capabilities, prioritizing secure connectivity, command and control, and deterrence. Expected deliveries in 2026 include FA-50 Block 70 fighters, Rajah Sulayman-class Offshore Patrol Vessels (OPVs), A-29B Super Tucanos, and the final BrahMos missile battery, significantly bolstering air, sea, and missile defense capabilities.

The force posture of the Philippines is increasingly geared towards archipelagic defense and maritime security, driven by persistent challenges in the South China Sea. The commencement of Exercise Salaknib 2026 with the US Army, focusing on jungle warfare, aviation, live-fire, and archipelagic defense, directly contributes to this posture. Furthermore, the finalization of over 500 joint military activities with the US for 2026 emphasizes Maritime Cooperative Activities (MCAs), which are vital for safeguarding freedom of navigation and enhancing interoperability in contested waters. The upcoming ASEAN-India Maritime Exercise 2026 will further strengthen regional maritime security cooperation. The planned deployment of six US fast-response Coast Guard cutters and the transfer of two new Coast Guard vessels to the Philippines in September 2026 will significantly enhance the Philippine Coast Guard's capabilities for search-and-rescue and maritime domain awareness, crucial for monitoring and responding to activities in its exclusive economic zone. These developments collectively demonstrate a concerted effort to build a credible defense posture through both indigenous modernization and strengthened alliances.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, the Philippines will likely continue to solidify its expanded network of security partnerships. The ratification of the SOVFA with France is expected to proceed, opening avenues for more frequent joint military exercises and intelligence sharing with a key European partner. The commencement of the ASEAN-India Maritime Exercise (AIME) 2026 in late September will further enhance multilateral maritime cooperation and interoperability, particularly in the Indo-Pacific. Domestically, the political landscape may remain somewhat volatile following the arrest warrant issued against Vice President Sara Duterte, though its direct impact on national security operations is expected to be limited. The increased funding for the AFP's modernization program will begin to translate into tangible capability enhancements, with continued deliveries of new assets.

Critical flashpoints and risk areas: The South China Sea remains the primary flashpoint. China's continued assertive actions, including "salami slicing" tactics and increased presence of its navy and coast guard, will likely lead to further confrontations with Philippine vessels. The deployment of US Coast Guard cutters to the region, while bolstering Philippine capabilities, could also be perceived by China as an escalation, potentially leading to increased rhetoric or more aggressive maneuvers. Internally, while the overall terrorist threat is declining, the persistence of ISIS-linked remnants, foreign fighters, and private armed groups in Mindanao, particularly in ungoverned spaces like the SPMS Box, poses an ongoing risk of localized violence and kidnapping. Cybersecurity threats to critical infrastructure will also remain a concern, necessitating the swift implementation of the recently approved National Cybersecurity and Critical Information Infrastructure Protection Act.

Indicators to monitor: Key indicators to monitor include the frequency and nature of maritime incidents in the West Philippine Sea, particularly around disputed features and resupply missions. The progress of the Philippines-France SOVFA ratification and any new defense agreements with other partners will indicate the pace of Manila's diversification strategy. The effectiveness of the AFP's modernization program in integrating new assets and enhancing deterrence capabilities will be crucial. Furthermore, monitoring the activities of terrorist groups and private armed groups in Mindanao, alongside the government's counter-terrorism efforts, will be essential for assessing internal security. Finally, the political stability surrounding the President-Vice President dynamic will be an important internal indicator.

Strategic recommendations: The Philippines should continue its strategy of strengthening alliances and diversifying partnerships to build a robust, multi-layered deterrence against external threats, particularly in the South China Sea. This includes actively pursuing more SOVFAs and defense cooperation agreements with like-minded nations. Domestically, sustained efforts are needed to address the root causes of terrorism and the influence of private armed groups in Mindanao, combining kinetic operations with socio-economic development and governance reforms. Accelerating the implementation of the National Cybersecurity Act and investing in advanced cyber defense capabilities are paramount to protect critical infrastructure from evolving digital threats. Finally, maintaining clear and consistent diplomatic messaging regarding its sovereign rights and adherence to international law will be crucial in shaping regional and international perceptions and garnering support for its positions.
