China's military drills near Taiwan raise war concerns.

China's military has completed three days of large-scale combat exercises around Taiwan, simulating sealing off the island in response to the Taiwanese president's trip to the US last week. The exercises were meant as a warning to self-governing Taiwan, which China claims as its own. Military experts say the exercises serve both as intimidation and as an opportunity for Chinese troops to practice sealing off Taiwan by blocking sea and air traffic, an important strategic option the Chinese military might pursue in the event it uses military force to take Taiwan.
