China Conducted Unannounced Taiwan-Adjacent Naval Drill With More Than 100 Vessels

Reuters reported that a Taiwanese security official confirmed China conducted unannounced military and coast guard exercises in early November involving more than 100 vessels across the western Pacific and around Taiwan. The official said the drills included simulated attacks on other militaries and cities, including Taiwan's. The official described the exercise as much larger than Justice Mission 2025, China's last formally named drills targeting Taiwan nearly a year earlier.

The official also said a Chinese submarine launched an intercontinental ballistic missile from the Yellow Sea into mainland China during the drills. Taiwan's Defense Minister Wellington Koo characterized the activity as area denial exercises involving an aircraft carrier and other naval formations. The account remains unconfirmed by Beijing, and the key details come from an anonymous Taiwanese security official speaking to Reuters.

The reporting connects the drills to questions about maritime chokepoints. The official suggested Beijing could be rehearsing shipping restrictions or blockade scenarios. Beijing has publicly called for peaceful reunification and has not renounced the use of force. CSIS analysis cited in the report says coast guard inspections, shipping restrictions and selective interdictions could be used below the threshold of armed conflict. The report says the drills took place ahead of U.S. midterm elections and an APEC summit in Shenzhen where Trump and Xi were expected to meet.

For firms and investors, the stakes are shipping risk and sourcing. The report argues that accelerating U.S.-China decoupling has pushed demand toward conflict-free critical material supply chains, particularly if shipping lanes near Taiwan become constrained by inspections, restrictions or conflict. Beijing gains coercive signaling and tests of blockade options; it also raises costs for companies dependent on routes around Taiwan.
