China warns it will take all necessary measures to safeguard its 'sovereignty and territorial integrity'.
It comes after the US House Speaker Nancy Pelosi touched down in Taiwan with the visit triggering increased tension between China and the US.
In response to the visit, China is set to hold military drills around Taiwan today, saying it'll conduct missile launches off the sea, east of the island.
Beijing had already been boosting its activity near the self-ruled territory.
While Taiwan's islands are said to have been put on full combat alert.
People in Taiwan itself are anxious over the US House Speaker's trip.
Members of the public told us the US just wants to spread its power and influence, not help them.
