The Taiwanese military is on high alert and is closely monitoring the Chinese People’s Liberation Army’s (PLA) air and naval deployments after Beijing yesterday reserved seven airspace areas east of its Zhejiang and Fujian provinces through Wednesday.

Beijing’s action was perceived as a precursor to a potential third “Joint Sword” military exercise, which national security experts said the PLA could launch following President William Lai’s (賴清德) state visits to the nation’s three Pacific allies and stopovers in Hawaii and Guam last week.

Unlike the Joint Sword military exercises in May and October, when Beijing provided detailed information about the affected areas, it has yet to formally announce any planned military drills.
