The dated exercise
Reuters reported on April 9, 2023 that China's military simulated precision strikes around Taiwan on the second day of drills. Taiwan's defense ministry said it was monitoring the activity. The exercises followed President Tsai Ing-wen's meeting with the U.S. House speaker during her American visit. These are the events behind the inherited address, rather than a new military warning.

A simulated attack describes training objectives, not confirmation that the represented targets were struck in a war. Reports of aircraft sorties also depend on the time window and the reporting authority; totals from different days cannot simply be added as unique aircraft. Reuters' April 10 follow-up reported the exercise ending and identified the Shandong carrier's participation, attributing the military's operational description to its command. The report also recorded Taiwan's response. The date and source matter whenever older footage or a short military headline circulates again.
