Following intensified activity, Taiwan reported that on October 11, 12 PLA aircraft sorties, six PLAN vessels, and three official ships operated around its territory, with five of the PLA sorties entering Taiwan’s southwestern ADIZ.

By 6 a.m. local time on October 12, Taiwan’s Ministry of National Defence said four PLA aircraft, six PLAN vessels, and three official ships were detected around Taiwan.

One PLA aircraft breached Taiwan’s southern ADIZ, while the remaining sorties split across the northern, central, and southwestern ADIZ regions.

The report highlights rising Chinese naval and coast guard activity near Taiwan and ongoing pressure on Taiwan’s leadership, with ROC Armed Forces maintaining monitoring and response.

Coast Guard Administration data show around 244 Chinese vessels detected around Taiwan in the past month, up from 55 in June and 30 in May, averaging about eight vessels daily, mainly Chinese coast guard ships.

Analysts from the US Naval War College note that civilian research vessels tied to China’s maritime operations can yield data useful for submarine and anti-submarine warfare, signaling broader escalation in Beijing’s efforts to assert jurisdiction near Taiwan.
