Marcos Jr.'s participation in the BRICS Summit also signaled a strategic diversification of diplomatic engagements, while internal security efforts continued to address persistent terrorist threats and maintain public order.
Key Security Developments
-
Heightened Rhetoric Against China in South China Sea
On September 9, 2026, Philippine Defense Secretary Gilberto Teodoro Jr. described China as the "biggest threat" to his country during a defense conference in Seoul, South Korea. This strong statement came after he received an audience note questioning the 2016 arbitral ruling on the South China Sea, which he publicly refuted, calling China's stance "desperate and ineffective." China's Foreign Ministry reacted sharply, accusing Philippine officials of "grandstanding and lies" and urging them to cease provocations. This incident underscores the Philippines' firm resolve in asserting its maritime claims and its increasing willingness to openly challenge Beijing's actions. -
Assertion of Maritime Rights and Awareness Campaign
President Ferdinand R. Marcos Jr. called on Filipinos on September 7, 2026, to unite in defending the country's maritime rights and protecting its waters as the Philippines observed Maritime and Archipelagic Nation Awareness Month (MANA Mo) 2026. The month-long observance, themed “Karapatan sa Karagatan, Sama-sama Nating Alagaan,” coincided with the anniversary of the 2016 South China Sea Arbitral Award, which affirmed the Philippines' sovereign rights within its exclusive economic zone. Foreign Affairs Secretary Ma. Theresa Lazaro further stated on September 9, 2026, that the government would continue countering claims in the West Philippine Sea with "legal clarity" and sustained diplomacy, emphasizing that international law and the 2016 Arbitral Award are not negotiable. -
Approval of Philippines-France Status of Visiting Forces Agreement (SOVFA)
On September 10, 2026, the Senate Committee on Foreign Relations approved the Status of Visiting Forces Agreement (SOVFA) between the Philippines and France, paving the way for its plenary ratification. This agreement, signed on March 26, 2026, is significant as it marks the first SOVFA between the Philippines and a European nation, expanding Manila's network of defense partners beyond its traditional allies. Defense Secretary Teodoro highlighted France's role as a major global arms supplier and its support for the 2016 Arbitral Ruling and freedom of navigation, emphasizing that such partnerships are crucial for strengthening the Philippines' deterrence against external pressures. -
President Marcos Jr.'s Participation in BRICS Summit
President Ferdinand R. Marcos Jr. departed for New Delhi, India, on September 11, 2026, to participate in the 18th BRICS Summit from September 12-13, 2026, in his capacity as the 2026 ASEAN Chair. This engagement signifies the Philippines' interest in diversifying its diplomatic and economic partnerships beyond traditional Western alliances and exploring opportunities with emerging economies. Ambassador Josel Ignacio stated that the Philippines stands to benefit from engaging with BRICS members, with President Marcos Jr. open to the possibility of the Philippines joining the bloc after rigorous study. -
Continued Military Modernization and Partnerships
The Philippines continues to deepen its defense ties and modernize its military capabilities. Defense Secretary Teodoro emphasized the need to expand defense partnerships due to territorial stress from China, stating it is "a matter of no choice." This includes ongoing acquisitions from South Korea, such as Malvar-class frigates and FA-50 fighter jets, and strengthening cooperation with the US, Japan, Australia, and New Zealand. Recent joint exercises, such as Exercise MASA 2026 (held "last month" but reported on September 10, 2026) with the US Marine Corps, involved simulating the BrahMos anti-ship missile, indicating a focus on enhancing anti-access/area denial capabilities. -
Cybersecurity Reinforcement Efforts
The Philippines is actively working to strengthen its cybersecurity posture. While PhilSec 2026, a major cybersecurity summit, occurred in June-July, its discussions on national cyber resilience and emerging threat landscapes remain relevant to ongoing efforts. The House of Representatives approved the National Cybersecurity and Critical Information Infrastructure Protection Act of 2026 in August, a priority measure aimed at protecting essential services from cyberattacks. The Department of Information and Communications Technology (DICT) continues to lead initiatives like Cybersecurity Awareness Month and the establishment of regional Security Operations Centers (SOCs) to elevate the nation's cyber defense. -
Persistent Counter-Terrorism Challenges
A report on September 12, 2026, indicated that the Philippines continues to face a declining yet persistent terrorist threat, 25 years after 9/11. While the country improved its ranking in the Global Terrorism Index (GTI) 2026 to 23rd out of 163 countries, ISIS-East Asia (ISIS-EA) and its affiliated factions, particularly the Dawlah Islamiyah-Maute Group (DIMG), remain the primary jihadist threat. The report also highlighted the growing concern of Private Armed Groups (PAGs) maintained by local politicians, which are now considered a new and dangerous category of terrorism, particularly in the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM). -
Internal Security Preparations for Rallies
Metro Manila police announced on September 10, 2026, that approximately 15,000 personnel would be deployed across the capital region in anticipation of rallies on September 21, the anniversary of the martial law declaration. Authorities are coordinating with rally organizers to ensure peaceful demonstrations and are on guard against individuals who might sow discord, vowing to exercise maximum tolerance. This proactive measure aims to maintain peace and order during potentially sensitive public gatherings.
Geopolitical Impact and Regional Dynamics
The Philippines' security developments this week underscore its increasingly assertive stance in the Indo-Pacific, particularly concerning the South China Sea. Defense Secretary Teodoro's direct labeling of China as the "biggest threat" at an international forum signals a hardening of Manila's diplomatic posture and a clear rejection of Beijing's expansive claims. This rhetoric, coupled with the continued emphasis on the 2016 Arbitral Award and the observance of Maritime and Archipelagic Nation Awareness Month, reinforces the Philippines' commitment to a rules-based international order and its sovereign rights. Such actions are likely to further strain relations with China, which has already condemned the Philippines' "provocations and theatrics."
Manila's strategy of deepening its network of strategic security partners is a direct response to these geopolitical pressures. The Senate committee's approval of the SOVFA with France is a significant step, diversifying the Philippines' defense alliances beyond its traditional partners like the United States, Japan, and Australia. This move, alongside ongoing defense cooperation with South Korea and the US, aims to bolster the Philippines' deterrence capabilities and enhance interoperability with like-minded nations committed to freedom of navigation and international law in the region. The Philippines' active role as the 2026 ASEAN Chair and President Marcos Jr.'s engagement with the BRICS Summit also highlight a broader diplomatic strategy to seek multilateral solutions and economic opportunities, while maintaining strategic autonomy amidst great power competition. These developments contribute to a more complex and interconnected regional dynamic, where the Philippines is actively shaping its security environment through a combination of assertive diplomacy and strategic partnerships.
Military and Defense Analysis
The Philippine military's force posture is increasingly geared towards maritime domain awareness and territorial defense, particularly in the West Philippine Sea. The emphasis on observing Maritime and Archipelagic Nation Awareness Month (MANA Mo) highlights the nation's identity and the critical importance of its maritime interests to national security and economic prosperity. This focus is directly linked to the ongoing disputes in the South China Sea, where the Armed Forces of the Philippines (AFP) and the Philippine Coast Guard (PCG) are at the forefront of asserting sovereign rights.
Modernization programs are a key component of the Philippines' defense strategy. The country continues to acquire advanced defense assets, with South Korea emerging as a significant partner, supplying Malvar-class guided-missile frigates and FA-50 fighter jets. The reported interest in acquiring more military drones further indicates a push towards enhancing intelligence, surveillance, and reconnaissance (ISR) capabilities, crucial for monitoring vast maritime territories. Defense spending trends are implicitly on an upward trajectory, driven by the need to upgrade an aging military and respond to evolving external threats. The training of US and Philippine marines with the BrahMos anti-ship missile, reported on September 10, 2026, demonstrates a clear intent to develop robust anti-access/area denial capabilities, particularly in deterring potential adversaries in disputed waters. These capability developments, supported by deepening alliances and visiting forces agreements, aim to build a more credible deterrent posture and enhance the AFP's ability to protect national interests.
Outlook and Forecast
In the short term (1-3 months), the Philippines is expected to maintain its assertive diplomatic stance regarding the South China Sea, continuing to challenge China's actions and rhetoric in international forums. This will likely involve further public statements from defense and foreign affairs officials, reiterating adherence to international law and the 2016 Arbitral Award. Simultaneously, Manila will continue to strengthen its security partnerships, with the ratification of the SOVFA with France anticipated to proceed, opening avenues for more joint military exercises and defense cooperation with European partners. The Philippines' role as ASEAN Chair will also see it actively promoting regional stability and rules-based order, potentially leveraging its position to foster greater consensus on maritime issues within the bloc.
Critical flashpoints and risk areas remain concentrated in the West Philippine Sea, particularly around features like Scarborough Shoal and Second Thomas Shoal, where maritime incidents with Chinese vessels could escalate. The increasing frequency and intensity of rhetorical exchanges raise the risk of miscalculation, even if direct military confrontation remains unlikely in the immediate future. Internally, the persistence of ISIS-affiliated groups and Private Armed Groups (PAGs) in Mindanao continues to pose a significant threat, requiring sustained counter-terrorism operations and a comprehensive approach to address underlying socio-economic issues. The upcoming Martial Law anniversary rallies in Metro Manila on September 21 also present a potential flashpoint for civil unrest, although authorities are taking proactive measures to ensure peaceful demonstrations.
Indicators to monitor include the nature and frequency of Chinese reactions to Philippine assertions, the progress of multilateral defense exercises and acquisitions, and the outcomes of diplomatic engagements, particularly with new partners like those in BRICS. The effectiveness of cybersecurity initiatives and the ability to mitigate internal security threats will also be crucial. Strategic recommendations for the Philippines include continuing its multi-faceted diplomatic approach to garner international support for its maritime claims, accelerating its defense modernization program with a focus on maritime domain awareness and anti-access/area denial capabilities, and implementing a holistic strategy to address the root causes of terrorism and private armed groups in the southern Philippines. Maintaining strong alliances while exploring new partnerships will be key to navigating the complex geopolitical landscape.
