China-Taiwan military pressure has escalated significantly throughout much of 2026, characterized by increased PLA incursions, naval presence, and strategic maneuvers. Throughout May and June, Taiwan observed a rising trend in aircraft and naval sorties. Notable incidents included the first mid-air refueling by a Chinese Y-20U in Taiwan's ADIZ in late May, and a surge of 32 aircraft sorties on 4 June. In June, the Chinese aircraft carrier Fujian transited the Taiwan Strait, signaling growing naval capabilities. During this period, Taiwan also continued sea trials for its first domestically built submarine. In July, tensions spiked as China conducted joint ‘Sea-2026’ naval exercises with Russia near Qingdao. This coincided with reports of over 110 Chinese military and Coast Guard vessels operating along the First Island Chain. By late August, high-intensity activity persisted, including PLA aircraft crossing the median line and the presence of the research vessel ‘Tongji’ in sensitive areas. In September, the PLA stepped up reconnaissance and surveillance operations in the airspace and waters east and southeast of Taiwan, utilizing combat aircraft and unmanned aerial vehicles (UAVs) to collect intelligence on force postures, including potential targets like air bases in Hualien. In response to increased pressure, Taiwan upgraded its maritime patrol capabilities around the Pratas Islands, completing a wharf project and stationing a new 100-tonne-class patrol boat to enhance deterrence. By mid-October, maritime confrontations intensified. The Taiwan Coast Guard reported a six-hour standoff near the Pratas Islands with Chinese Coast Guard vessel ‘3102’, which entered restricted waters with its AIS deactivated and broadcasted propaganda. This followed earlier reports of coordinated ‘maritime harassment’ involving 16 Chinese vessels. Additionally, US-China tensions expanded in the South China Sea as China deployed forces to track the USS Charleston near Sabina Shoal, an action the US and Philippines defended as routine operations in international waters.
