Key Security Developments

• Diplomatic Assertion at the UN General Assembly
  On September 27, 2026, Foreign Affairs Secretary Maria Theresa Lazaro addressed the 81st United Nations General Assembly, advocating for the resolution of global conflicts through diplomacy and international law, rather than force. She emphasized that this approach also applies to maritime disputes, citing the 2016 South China Sea Arbitral Award as a demonstration of how international law provides peaceful means to resolve differences. On September 28 and October 2, the Philippine delegation firmly denied China's accusations of attempting to expand its maritime territory, asserting that the country is acting within its rights under the "final and binding" arbitral ruling. This highlights the Philippines' consistent diplomatic strategy to leverage international law in its territorial disputes.

• Escalating Maritime Tensions in the South China Sea
  The period saw continued friction in the South China Sea. On September 26, China urged the Philippines to cease provocations, warning that the China Coast Guard (CCG) would safeguard its territorial sovereignty and maritime rights, following a Philippine supply mission to Ren'ai Jiao (Second Thomas Shoal) on September 25. On September 27, the Chinese PLA Southern Theater Command organized a joint naval and air exercise around Huangyan Dao (Scarborough Shoal), describing it as a "stern warning" in response to the Philippines' actions. Furthermore, an updated geopolitical risk assessment on October 1, 2026, noted that a resupply mission to the BRP Sierra Madre at Second Thomas Shoal was suspended on September 24 after CCG cutters and People's Liberation Army Navy (PLAN) warships obstructed it, marking an unprecedented involvement of PLAN warships in such incidents.

• Philippine Coast Guard Challenges Chinese Research Vessel
  On October 1, 2026, the Philippine Coast Guard (PCG) deployed its largest vessel, BRP Teresa Magbanua, and an aircraft to challenge a Chinese research ship, Jia Hai Ke 7, operating approximately 37 nautical miles northwest of Itbayat Island in Batanes, near Taiwan. The PCG's operation "disrupted the vessel's unauthorized marine scientific research and compelled it to leave its loitering position". The Department of Foreign Affairs (DFA) on October 2 firmly rejected China's assertion of sovereign rights in these waters, emphasizing that no consent was given for such research. This incident underscores the Philippines' proactive stance in asserting its exclusive economic zone (EEZ) against perceived Chinese incursions.

• Commencement of Exercise Salaknib 2026
  Exercise Salaknib 2026 officially commenced on September 26, reaffirming the enduring partnership between the United States Army and the Armed Forces of the Philippines (AFP). Hosted in the Philippines, this annual exercise involves thousands of U.S. and Philippine soldiers training together in complex, multi-domain events, including jungle warfare, aviation operations, and live-fire drills. Regional partners such as the Australian Army, Japan Ground Self-Defense Force, and New Zealand Defence Force are also participating as subject matter experts and observers, reinforcing shared security interests in a free and open Indo-Pacific.

• Conclusion of Pacific Partnership 2026
  The U.S. Navy-led humanitarian and disaster preparedness mission, Pacific Partnership 2026 (PP26), concluded its final mission stop in Tacloban City, Leyte, on September 28, 2026, with a wreath-laying ceremony. Beginning September 21, 376 service members from the U.S. and partner nations (Canada, Germany, Japan, New Zealand, UK) collaborated with the AFP on engineering, disaster management, and medical activities. This year's mission in the Philippines was particularly significant as it marked the 75th anniversary of the U.S.-Philippines alliance, codified by the Mutual Defense Treaty.

• Philippine Army Submits Missile Acquisition Plans
  On September 26, 2026, the Philippine Army chief, Lt. Gen. Donald Gumiran, announced that the Army has submitted plans to the Department of National Defense (DND) for the acquisition of missile systems. While no specific weapon or supplier has been identified, this move signifies a crucial step in enhancing the Army's long-range precision strike capabilities and overall defense posture, aligning with the AFP's modernization program.

• Hanwha Ocean Boosts Submarine Bid
  South Korean shipbuilder Hanwha Ocean upgraded its proposal to build submarines for the Philippine Navy, as reported on October 2, 2026. Competing with European shipbuilders, Hanwha offered the Jangbogo-III PN, a variant of a submarine developed for the Republic of Korea Navy, which is approximately 77 meters long, 9.7 meters wide, and has a surface displacement of about 2,800 tons, utilizing lithium-ion batteries. This development is part of the Philippines' ongoing efforts to acquire a credible submarine capability for maritime defense.

• Counter-Terrorism Efforts and Convictions
  The Department of Justice (DOJ) Task Force on Anti-Terrorism secured three convictions against terrorists, as announced on September 24, 2026. This demonstrates the government's continued commitment to combating terrorism and upholding justice. Additionally, on September 26, the Villaba Municipal Police Station highlighted its ongoing anti-terrorism campaign, emphasizing the threat of terrorism to national security.

• School Security Threats
  On October 1, 2026, multiple educational institutions, including De La Salle-College of Saint Benilde, De La Salle University-Dasmariñas, and Mapúa Malayan Colleges Laguna, suspended classes due to security threats. These incidents add to a growing string of school scares, prompting the Philippine National Police (PNP) to consider nationwide adoption of rapid response systems to improve communication between campuses and law enforcement.

• Strengthening Ties with Poland and Panama
  The Philippines is set to host Polish President Karol Nawrocki for a state visit from October 5 to 8, 2026, marking the first time a Polish head of state will visit the country. Discussions are expected to cover defense and security, trade, and other areas of cooperation, building on previous meetings like the inaugural Philippines-Poland Joint Defense Cooperation Committee in July 2026 and the 7th Philippines-Poland Political Consultations in September 2026. Separately, the Philippines and Panama held their inaugural Political Consultations on October 2, aiming to strengthen bilateral relations, particularly in trade, investment, and maritime cooperation.

Geopolitical Impact and Regional Dynamics

The Philippines' security developments during this period significantly underscore its pivotal role in the Indo-Pacific region, particularly concerning the South China Sea. Manila's firm diplomatic stance at the UN General Assembly, reiterating the 2016 arbitral award and rejecting China's expansive claims, signals a continued commitment to a rules-based international order. This approach, however, directly clashes with China's assertions, leading to escalating tensions as evidenced by the PLA's exercises near Huangyan Dao and the unprecedented involvement of PLAN warships in obstructing a resupply mission to Second Thomas Shoal. These incidents highlight a dangerous "controlled violence" baseline in the disputed waters, where the risk of miscalculation remains high.

The robust military cooperation with major powers like the United States, Japan, Australia, and New Zealand through exercises like Salaknib 2026 and the recently concluded Pacific Partnership 2026, reinforces the Philippines' alliance network. These exercises, which include complex multi-domain training and humanitarian assistance, are crucial for enhancing interoperability and collective deterrence against common threats in the region. The U.S.-Philippines alliance, celebrating its 75th anniversary this year, remains a cornerstone of regional stability, with ongoing commitments to defense cooperation and economic development, including investments in Enhanced Defense Cooperation Agreement (EDCA) sites. The strengthening of Balabac island near Sabah, part of the EDCA network, also raises security considerations for Malaysia, indicating a broader regional impact of the Philippines' defense posture.

The Philippines' active diplomatic engagement extends beyond traditional allies, as seen in the upcoming state visit of the Polish President and inaugural political consultations with Panama. These efforts aim to diversify partnerships and broaden support for its foreign policy objectives. However, the ongoing South China Sea disputes continue to be a dominant factor shaping the Philippines' regional dynamics, with China consistently urging Manila to return to a bilateral track and cease "provocations". The Philippines' role as ASEAN Chair in 2026 also places it in a delicate position, as the regional bloc's self-imposed deadline for a South China Sea Code of Conduct is likely to pass without a binding instrument, further highlighting the challenges in managing regional maritime security.

Military and Defense Analysis

The Armed Forces of the Philippines (AFP) is actively pursuing a comprehensive modernization program, known as Horizon 3, to enhance its external defense capabilities. The Philippine Army's submission of plans to acquire missile systems on September 26, 2026, signifies a strategic move towards developing long-range precision strike capabilities, which are crucial for territorial defense and deterrence in contested maritime areas. This complements earlier reports of the military receiving FA-50 Block 70 fighters, Rajah Sulayman-class Offshore Patrol Vessels (OPVs), A-29B Super Tucanos, and the final BrahMos missile battery in 2026, all aimed at bolstering air, sea, and missile capabilities.

The ongoing bid for a submarine deal, with Hanwha Ocean upgrading its proposal for the Jangbogo-III PN submarine, indicates a strong commitment to acquiring a credible underwater defense capability. Such an acquisition would significantly enhance the Philippine Navy's maritime security and patrol power, particularly in the South China Sea. Furthermore, the strengthening of military infrastructure on Balabac island in southern Palawan, which is part of the EDCA network and has hosted multinational exercises, demonstrates a focus on strategic locations for archipelagic defense and regional security.

Defense spending trends are likely to reflect these modernization priorities, with significant appropriations, such as the additional $144 million in Fiscal Year 2026 for EDCA sites, indicating sustained investment in defense infrastructure and capability development. The participation in joint exercises like Salaknib 2026 and Pacific Partnership 2026 not only enhances combat readiness and interoperability with allies but also provides opportunities for the AFP to refine its tactics, techniques, and procedures across various domains, from jungle warfare to maritime security and disaster response. The activation of the Acquisition and Cross-Servicing Agreement (ACSA) with Japan, which came into force on August 22, 2026, will also boost the Philippines' sustainment capabilities and support its modernization program.

Outlook and Forecast

Short-term trends (1-3 months): The immediate future will likely see continued maritime confrontations in the South China Sea, particularly around Second Thomas Shoal and Scarborough Shoal. China's assertive actions, including the use of PLAN warships in obstruction missions, suggest a hardening of its stance, which the Philippines will continue to counter through diplomatic protests and freedom of navigation operations. The Philippines will likely maintain its strong diplomatic offensive at international forums, reiterating the 2016 arbitral award. Military exercises with allies, such as the ongoing Salaknib 2026, will continue to be a prominent feature, enhancing interoperability and signaling collective deterrence. The state visit of the Polish President in early October will further diversify diplomatic and defense cooperation. Domestically, authorities will remain vigilant against internal security threats, including terrorism and school-related incidents.

Critical flashpoints and risk areas: The Second Thomas Shoal and Scarborough Shoal remain critical flashpoints, with the potential for accidental collisions or more direct confrontations between Philippine and Chinese vessels. The waters off Batanes, where the PCG recently challenged a Chinese research vessel, could also become an area of increased scrutiny and potential incidents. The strengthening of Balabac Island and other EDCA sites, while enhancing Philippine defense, may also draw increased attention and potential counter-responses from regional actors, particularly Malaysia. Internally, the threat of terrorism, though degraded, persists in certain areas of Mindanao and the Sulu Archipelago, requiring continuous counter-terrorism operations. School security threats, as recently observed, indicate a need for enhanced vigilance and rapid response mechanisms in urban centers.

Indicators to monitor: Key indicators to monitor include the frequency and intensity of maritime incidents in the South China Sea, particularly around disputed features. Any changes in the involvement of Chinese naval assets in "grey zone" operations will be significant. The progress of the Philippines' defense modernization program, including specific acquisitions like missile systems and submarines, will indicate its long-term strategic direction. Statements and actions from the U.S. and other allies regarding their commitment to regional security and freedom of navigation will also be crucial. Domestically, the effectiveness of counter-terrorism operations and the government's response to security threats in public spaces, including schools, will reflect internal stability.

Strategic recommendations: The Philippines should continue to strengthen its alliances with like-minded nations, particularly the United States, Japan, and Australia, to bolster its deterrence capabilities and ensure a collective response to regional challenges. It is imperative to accelerate defense modernization efforts, focusing on acquiring credible maritime and air assets, including missile systems and submarines, to protect its sovereign rights and EEZ. Diplomatically, Manila should persist in its rules-based approach, consistently invoking international law and the 2016 arbitral award in all relevant forums, while also exploring new partnerships to diversify support. Internally, continued investment in counter-terrorism capabilities and enhanced intelligence activities are necessary to address persistent threats in Mindanao and the Sulu Archipelago. Furthermore, a proactive and coordinated approach to cybersecurity and critical infrastructure protection is essential, given the increasing complexity of modern threats.
