A Chinese military unit based in a city that lies opposite self-ruled Taiwan has carried out live fire exercises and landing drills, state television reported just days after an independence-leaning opposition party won elections in Taiwan.
China considers Taiwan a wayward province, to be brought under its control by force if necessary. Defeated Nationalist forces fled to Taiwan in 1949 after the Chinese civil war.
In a piece late on Wednesday, state television's military channel said the 31st Group Army, based in the southeastern Chinese city of Xiamen, had carried out the drills in "recent days", though it did not give an exact location.
It showed amphibious armored vehicles ploughing through the sea towards a landing spot, helicopters firing missiles at locations on shore and soldiers parachuting down from helicopters.
The report made no direct mention of the Taiwan election. China's Defense Ministry did not immediately respond to a request for comment.
Taiwan's Defense Ministry said it was "aware of the information", and declined further immediate comment.
Xiamen sits opposite Taiwan, and right off Xiamen's coast is Kimnen, an island controlled by Taiwan since 1949 and until the late 1970s a place regularly shelled by China.
Since Tsai Ing-wen and her Democratic Progressive Party won by a landslide Taiwan's presidential and parliamentary elections on Saturday, China has warned against any moves towards independence and that it will defend the country's sovereignty.
Tsai has said she will maintain peace with China, and Chinese state-run media has also noted her pledges to maintain the "status quo" with China.
China's military, the world's largest, held live-fire drills in the Taiwan Strait in September, though Taiwan's Defense Ministry described them at the time as routine.
Taiwan's military has warned that China is building two new aircraft carriers and has practised attacks on targets modeled on places in Taiwan. China confirmed on New Year's Eve it was indeed building one new carrier, to add to its existing one.
