Update(9:57ET): Less than a half-day after Nancy Pelosi's departure from Taiwan on a US Air Force plane, a large group of 27 Chinese PLA planes breached Taiwan's air defense identification zone Wednesday, crucially with at least 22 of the aircraft reported as having crossed the Taiwan Strait "median line".

A map posted to Taiwan's Ministry of National Defense showed the brief crossovers by the PLA jets. In response, the ministry said it issued radio warnings and readied air defense missile systems to monitor the activities. Taiwan previously said it won't hesitated to deploy its armed forces to thwart "enemy threats". Already as Pelosi's plane was inbound yesterday from Malaysia Chinese planes and ships had buzzed the median line, which demarcates what the self-ruled island deems its own territorial waters.
