Taiwan's Defense Ministry reported on Monday that 13 Chinese Navy vessels and 39 aircraft were spotted "around our surrounding region." It added that its armed forces responded by engaging combat air patrol aircraft, naval vessels, and land-based missile systems.
The ministry stated that 21 of the detected aircraft flew "on the east part of the median line of the Taiwan Strait" and on the southwest of its Air Defense Identification Zone.
China's military drills near Taiwan ended on Sunday, but Beijing announced it will immediately start new exercises, drawing condemnation from Taiwan.
