China has held its biggest-ever show of military force in the air and seas around Taiwan, including the firing of ballistic missiles.
The military exercises followed a visit to the island by the Speaker of the US House of Representatives, Nancy Pelosi.
China sees Taiwan as a breakaway province that will eventually be under Beijing's control again.
However, the self-ruled island sees itself as distinct from the mainland, with its own constitution and democratically-elected leaders.
China's President Xi Jinping has said "reunification" with Taiwan "must be fulfilled" - and has not ruled out the possible use of force to achieve this.
