# China-Taiwan military pressure escalation continues > Live situation record from CLSTR: https://clstr.news/situations/taiwan-china-adiz-incursions > Updated: 2026-09-05T09:19:21.000Z. Sources: 131. Developments: 33. 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. China also conducted a simulated nuclear warhead launch from a submarine in the Pacific, which it defended as routine training. By late August, high-intensity activity persisted, including the detection of the Chinese research vessel ‘Tongji’ near sensitive areas. Data from the Taiwan Coast Guard reveals a record surge in Chinese government maritime activity in July, with 244 vessels—including coast guard and scientific research ships—detected near Taiwan's main island, averaging nearly eight per day. Including activity near offshore islands like Kinmen and Matsu, the total rises to 425 vessels. Analysts describe these as ‘grey zone’ tactics to assert jurisdiction and gather hydrographic data for potential submarine warfare. In early September, Taiwan detected 20 aircraft sorties, six PLAN vessels, and five official ships during a “Joint Combat Readiness Patrol” and “Air-Sea Joint Drill.” Notably, 12 aircraft crossed the median line. Taiwan’s Ministry of National Defense suggests Beijing is focusing on perfecting “blockade and control joint” operations rather than immediate large-scale invasion. ## Claims - Earlier in the week, Taiwan detected three PLA aircraft sorties, seven PLAN vessels and four official ships.
