What’s Happening

The probability of a China x Philippines military clash before 2027 currently stands at 19% YES, reflecting heightened tensions in the South China Sea following recent diplomatic and military developments. Philippine President Ferdinand Marcos Jr. is scheduled to visit Japan from May 26 to 29, 2026, a trip described as occurring at a "particularly sensitive moment" as the Indo-Pacific security environment is reshaped by intensifying great power competition. The visit aims to strengthen bilateral ties rooted in shared democratic values, but it also underscores Manila’s deepening alignment with U.S. allies amid ongoing disputes with Beijing over the Second Thomas Shoal and other features in the South China Sea. Analysts note that Marcos’s outreach to Tokyo could further strain relations with China, which has repeatedly warned against foreign military involvement in the region. [Eurasia Review, May 22]

Recent military exercises have added a concrete dimension to the risk of a China x Philippines military clash. In May 2026, the U.S. military and allied forces conducted large-scale wargames in the Philippines, including counter-invasion drills and a strike on a decommissioned Philippine vessel. Adm. Samuel Papa, a top U.S. commander, described the exercise as a "rehearsal for a Pacific fight," explicitly simulating the defense of a Pacific ally from invasion. The drills involved missiles, rockets, artillery, and drones, signaling a shift from routine patrols to active combat preparation. Meanwhile, a Pentagon report has identified 2027 as the year China could have sufficient military resources to launch a major operation, though former Defense Secretary Robert Gates recently stated he does not believe Beijing will attack Taiwan soon, preferring a "Hong Kong-style transition." This divergence in assessments highlights the uncertainty surrounding China’s strategic timeline. [Business Insider, May 20] [New York Post, May 18]

The structural factor that will determine the likelihood of a China x Philippines military clash before 2027 is the interplay between Beijing’s expanding military capabilities and its willingness to use force. A Reuters report revealed that China’s military secretly trained approximately 200 Russian soldiers in 2025, some of whom later fought in Ukraine, undermining Beijing’s claims of neutrality and raising concerns about its global power projection. Additionally, NASA head Jared Isaacman predicted on May 19, 2026 that China will conduct a crewed mission around the moon in 2027, signaling an accelerated space program that mirrors its terrestrial ambitions. These developments suggest China is building capacity across multiple domains, but whether it will risk a direct confrontation with the Philippines—a treaty ally of the U.S.—remains contingent on diplomatic off-ramps, such as the proposed Code of Conduct for the South China Sea, which has stalled in negotiations.
