Taiwan announced that China's military drills appear to simulate an attack on the self-ruled island, after multiple Chinese warships and aircraft crossed the median line of the Taiwan Strait after US House Speaker Nancy Pelosi's visit to Taipei that infuriated Beijing. 

 In reaction to the Chinese drills, Taiwan's armed forces sent out a warning, sent out air and naval patrols surrounding the island, and turned on land-based missile systems, as a tweeted message from Taiwan's Ministry of National Defense.

Following Pelosi's visit to Taiwan earlier this week, China began conducting live-fire military drills, claiming that this was a violation of the "one-China" policy. Taiwan is considered a breakaway province by China, which intends to take it by force if necessary. China views foreign dignitaries visiting Taiwan as an acknowledgment of China's sovereignty.
According to Taiwan's Central News Agency, the Taiwanese army claimed to have spotted four unmanned aerial vehicles flying close to the offshore county of Kinmen on Friday night.

According to Taiwan's Kinmen Defense Command, the four drones, which Taiwan assumed to be Chinese, were seen flying over the waters around the Lieyu Island and Beiding islet as well as the Kinmen island group. The military of Taiwan responded by launching warning flares.

In the Taiwan Strait, which separates the two sides that separated amid civil war in 1949, the Kinmen group of islands, also known as Quemoy, is located just 10 kilometres (6.2 miles) east of the Chinese coastal city of Xiamen in the Fujian province.
Chinese military drills started on Thursday and are scheduled to continue through Sunday. In an echo of the most recent significant Chinese military exercises in 1995 and 1996 intended to intimidate Taiwan's leaders and people, the drills have so far involved missile strikes on targets in the seas north and south of the island.

Taiwan has activated its military and held civil defence drills, while the US has stationed a large number of naval assets nearby. The "one-China" policy, which acknowledges Beijing as the government of China but permits informal relations and defence links with Taipei, is still a priority for the US, according to Pelosi and the Biden administration. Pelosi's visit was discouraged but not prevented by the government.
