How the Philippines is Building a Global Defense Network to Counter China

The security architecture of the Indo-Pacific is undergoing a fundamental rewiring. For decades, the region's defense relied on a "hub-and-spoke" model, with the United States serving as the central guarantor of security for individual Asian allies who rarely coordinated directly with one another.[5]

But as tensions in the South China Sea reach a boiling point, the Philippines is aggressively moving to rewrite that playbook. Under President Ferdinand Marcos Jr., Manila is finalizing a sweeping network of bilateral defense pacts with Japan, Australia, and France, transforming the archipelago into the anchor of a new, multinational deterrence strategy.[1][5]

The catalyst for this diplomatic offensive is the escalating friction within the Philippines' Exclusive Economic Zone (EEZ). Over the past two years, the Chinese Coast Guard and maritime militia have intensified their harassment of Philippine civilian and government vessels operating in the crucial waterway.[2]

Tactics have escalated from shadowing and radio warnings to the use of military-grade lasers, high-pressure water cannons, and deliberate vessel rammings. These clashes frequently occur near contested features like the Second Thomas Shoal, where Manila maintains a grounded World War II-era ship to assert its territorial claims against Beijing's expansive maps.[2][5]

In response, Philippine Defense Secretary Gilberto Teodoro Jr. has spearheaded a strategy of "security diversification." The goal is to build a "lattice" of overlapping military partnerships that complicate Beijing's strategic calculus and ensure that any conflict in the South China Sea would immediately entangle multiple global powers.

The most significant breakthrough in this strategy occurred in March 2026, when the Philippines and France signed a Status of Visiting Forces Agreement (SOVFA) in Paris. The landmark treaty marks Manila's first such pact with a European nation.[1]

The French agreement provides a legal framework for the two militaries to conduct joint exercises on each other's territory. For France, which maintains significant overseas territories and a permanent military presence in the Indo-Pacific, the pact secures vital territorial access to the Philippines during times of regional instability.

This European integration builds upon a rapidly deepening alliance with Japan. In July 2024, Tokyo and Manila signed a Reciprocal Access Agreement (RAA), a historic milestone that allows Japanese Self-Defense Forces to deploy on Philippine soil.[2][4]

The Japan-Philippines partnership has only accelerated since. In January 2026, the two nations concluded an Acquisition and Cross-Servicing Agreement (ACSA), enabling their militaries to share ammunition, fuel, and supplies on a tax-free basis during joint operations and disaster response efforts.[4]

Tokyo's involvement goes beyond logistics. Having recently lifted its post-war ban on lethal weaponry exports, Japan is now in advanced talks to transfer upgraded destroyers to the Philippine Navy, complementing previous donations of coastal surveillance radars and rigid-hull inflatable boats.[4]

Australia, which has held a SOVFA with the Philippines since 2007, is also upgrading its commitments. In 2026, Canberra and Manila advanced plans for a new defense agreement that includes the construction and maintenance of military infrastructure at five locations on the Philippine island of Luzon.[3]

The physical manifestation of this new alliance network was on full display during the Balikatan 2026 military exercises. Traditionally a bilateral drill between the U.S. and the Philippines, this year's iteration transformed into a massive multilateral show of force.[3][4]

Over 10,000 troops participated in full-spectrum operations across the Philippine archipelago. Crucially, Japan deployed troops on Philippine territory for the first time since World War II, transitioning from its historical role as a humanitarian observer to an active participant in combat interoperability drills.[3][4]

France, Canada, and New Zealand also joined the exercises, illustrating the functional reality of Manila's new security network. By bringing these nations into the fold, the Philippines is signaling that the defense of the South China Sea is no longer just a bilateral American concern, but a global imperative.[3]

This diversification also serves as an insurance policy. With the United States increasingly stretched by conflicts in the Middle East and Eastern Europe, and facing domestic political volatility regarding its foreign commitments, Manila is ensuring it has secondary security guarantors.

Beijing has reacted to this diplomatic encirclement with predictable hostility. Chinese officials have repeatedly condemned the agreements, accusing the Philippines of acting as a proxy for Western hegemony and attempting to build an "Asian NATO."[2][3]

During the Balikatan exercises, the People's Liberation Army Southern Theater Command conducted high-profile combat readiness drills. China deployed the Liaoning aircraft carrier and H-6 bombers fitted with supersonic cruise missiles to the region, a clear attempt to maintain a deterrent threshold against the growing coalition.[4]

Despite the intimidation, the Marcos administration shows no signs of reversing course. The Philippines continues to lean heavily on the 2016 international arbitral ruling—which invalidated China's expansive historic claims under the United Nations Convention on the Law of the Sea (UNCLOS)—as the normative foundation for its new alliances.[1]

The ultimate test of this "lattice" strategy remains unanswered. While the presence of French, Japanese, and Australian forces undoubtedly raises the geopolitical stakes for Beijing, it is unclear whether these pacts will successfully deter Chinese aggression or simply accelerate the militarization of one of the world's most vital commercial waterways.[5]
