Tensions have spiked between China and the island since Sunday, when Taiwan F-16s shadowed Chinese fighters and bombers which flew around the island. Beijing claims Taiwan as its territory, to be taken by force if needed.
On Monday, Taiwan's air force scrambled after Chinese jets briefly crossed an unofficial middle line in the Taiwan Strait, which both sides' forces generally stay on their respective sides of.
In a statement late on Monday, the People's Liberation Army Eastern Theatre Command said its forces carried out "air-ground assault and fire support drills to further refine and test their multi-service joint combat capabilities".
