U.S. Military Expands Philippines War Games to Deter China

The most important fact about Balikatan isn’t its size — it’s what the growth curve reveals: an alliance that has quietly shifted from an annual training ritual into the visible backbone of American deterrence strategy in the Western Pacific, with the Philippines no longer a junior partner hosting drills but a frontline participant shaping them.

Key Points

Balikatan, the annual U.S.-Philippines exercise, has grown from a bilateral training event into a multinational deterrence platform involving 17,000–18,000 troops and, in some cycles, seven nations.
Recent iterations have moved beyond classroom-style interoperability drills to live-fire missile strikes, simulated island-invasion scenarios, and maneuvers explicitly staged near Taiwan.
China has consistently protested the drills as destabilizing, while the U.S. and Philippine militaries frame them as a direct response to Beijing’s own assertiveness in the South China Sea.
Allied participation has broadened well beyond the original two-country format, pulling in Japan, Australia, Canada, France, New Zealand, and the UK.
Analysts are divided on whether the buildup restrains Chinese behavior or, by Beijing’s own logic, provokes the confrontation it’s designed to prevent.

From Training Exercise to Strategic Signal

Balikatan — Tagalog for “shoulder to shoulder” — began decades ago as a modest bilateral training rotation rooted in the 1951 U.S.-Philippines Mutual Defense Treaty. For most of its history it drew little outside attention: humanitarian-assistance scenarios, small-unit tactics, logistics rehearsals. That changed dramatically in the past several years. The U.S. Embassy in Manila described the 2024 iteration as “the 39th iteration of Balikatan, the largest annual bilateral training exercise between the two Allies,” running from April 22 to May 10 and involving the fullest scope of cooperation the alliance had yet attempted. The Armed Forces of the Philippines called it, at closing ceremonies in Camp Aguinaldo, “the culmination of the most comprehensive iteration of the annual defense exercise yet”.

The scale kept climbing. Reporting on subsequent cycles describes nearly 18,000 troops taking part, with VOA calling one iteration the Philippines’ and America’s “largest-ever joint military exercises,” explicitly framed as an allied response to “growing Chinese assertiveness in the region”. Bloomberg’s coverage of a later cycle put the multinational troop count above 17,000, drawn from seven countries including Canada, Australia, New Zealand, and France, with Japan joining for the first time. That last detail matters: Japan’s inclusion followed Tokyo’s own landmark policy shift permitting exports of lethal defense equipment to allied nations, ending decades of postwar pacifist restriction — a change that dovetails directly with the alliance’s expansion.

What the Drills Actually Involve

The substance of the exercises has hardened along with their headcount. Early Balikatan rotations emphasized interoperability — getting American and Filipino units to communicate, coordinate logistics, and operate under shared command structures. Recent cycles have added combat realism: live missile and artillery launches simulating a repelled invasion in the waters north of the Philippines, directly across from Taiwan. Reuters described one such cycle in which “U.S. and Philippine military forces conducted missile and artillery launches to counter a simulated invasion in the northern waters of the Philippines, adjacent to Taiwan”. A Philippine military spokesman, Col. Michael Logico, put the intent plainly: “We’re dead serious about protecting our territory — that’s why we do these Balikatan exercises”. A U.S. general overseeing the exercises told reporters the allied force could “repel aggression” in the theater as the drills opened.

The geography has expanded alongside the firepower. Exercises have moved into contested reaches of the South China Sea and onto small Philippine islands positioned near Taiwan, described in one Reuters dispatch as testing “real-world readiness” through maritime strike drills on “a secluded Philippine island adjacent to Taiwan”. Multilateral maneuvers with Australia, Canada, and Japan have become routine rather than exceptional — a pattern AP described as a “demonstration of strength” in waters where “China has intensified its territorial assertions”. The Philippine military has also joined separate, smaller-scale joint patrols with Australia multiple times in a single year, underscoring how frequent this cooperation has become outside the flagship Balikatan window.

Why Washington and Manila Frame This as Necessary

The official rationale, articulated consistently across U.S. Embassy statements, Pentagon releases, and joint diplomatic communiqués, is deterrence rather than provocation. A joint statement from the Philippines-United States Bilateral Strategic Dialogue affirmed both governments’ “unwavering commitment to uphold a free, open, prosperous, and secure Indo-Pacific, grounded in mutual respect for sovereignty, territorial integrity, international law, and the peaceful resolution of disputes”. U.S. commanders overseeing the exercises have used similar language, describing the goal as denying any adversary the ability to achieve objectives through coercion, and casting the Indo-Pacific as the defining strategic theater of this century.

This framing rests on a specific grievance: repeated incidents involving Chinese coast guard and maritime militia vessels in waters the Philippines claims under international law, including a 2016 arbitral ruling that Beijing has never accepted. Manila’s pivot toward more visible, more frequent, and more muscular joint exercises reflects a judgment — shared by successive Philippine administrations — that quiet diplomacy alone has not slowed Chinese activity in disputed reefs and shoals. The alliance’s answer has been visibility itself: publicizing troop numbers, live-fire drills, and multinational participation as a signal that any attempt to alter the status quo by force would draw a coordinated response.

Beijing’s Response and the Genuine Point of Disagreement

China’s objections are consistent and on the record. Its foreign ministry has repeatedly characterized the drills as destabilizing rather than defensive. One statement carried by China Daily said Beijing “expressed concern over the annual military exercises involving the United States, the Philippines and Japan, stressing that what the Asia-Pacific region needs most is peace and stability, not the introduction of external forces that create division and confrontation”. Reuters reported a similar warning ahead of another cycle, with Beijing cautioning that expanding military partnerships “risk regional trust” and could “erode trust and exacerbate divisions within the region”. Chinese Foreign Ministry spokesperson Lin Jian has voiced comparable objections directly tied to specific exercise announcements.

Here is where genuine, substantive disagreement exists — not about whether the drills occurred, which is uncontested, but about their strategic effect. Analysts quoted by VOA argue the buildup demonstrates “inter-alliance cohesion” that strengthens deterrence. Others are less certain the effect runs one direction. A regional-affairs analysis asked directly whether “China’s Defiance Show[s] the Limits of US Deterrence in the South China Sea,” noting that expanded exercise areas and weapons deployments have prompted “a surge in Chinese vessel presence” rather than restraint. This is the honest tension at the center of the story: the same demonstrations built to reassure allies and constrain Chinese behavior can just as plausibly read, from Beijing’s vantage point, as justification for its own military expansion — a dynamic scholars studying the South China Sea have termed a “mutual deterrence equilibrium” that neither side fully controls.

What This Means Going Forward

The trajectory is unlikely to reverse. Each successive Balikatan cycle has broadened participation, hardened the exercise content, and moved the geographic focus closer to Taiwan — a pattern consistent across multiple years of independent reporting rather than a single anomalous event. The addition of Japan, whose own defense posture has shifted markedly, and the recurring involvement of Australia, Canada, France, and New Zealand suggest the informal coalition backing the Philippines is widening rather than narrowing. The Diplomat’s analysis of a recent 18-day iteration, gathering 17,000 personnel primarily from the Philippines, Japan, and the United States, described an “increasingly strategically relevant Southeast Asian archipelago” — language that captures how central this stretch of ocean has become to broader Indo-Pacific planning.

For the region, the practical stakes are straightforward even if the long-term outcome is not. Larger, more frequent, more public exercises raise the cost of miscalculation even as they aim to lower the odds of one. Whether that trade nets out as stabilizing or as an accelerant of the very confrontation it seeks to prevent remains the field’s central, unresolved question — one that will be tested, cycle after cycle, in the waters between Luzon and Taiwan.
