China's air force has carried out 16 rounds of exercises close to Taiwan in the last year or so, Taiwan's defense ministry said on Tuesday, warning that China's military threat was growing by the day.

China considers self-ruled and democratic Taiwan to be its sacred territory and has never renounced the use of force to bring what it views as a wayward province under Chinese control.

China has taken an increasingly hostile stance toward Taiwan since Tsai Ing-wen from the island's pro-independence Democratic Progressive Party won last year's presidential election.
