The Chinese military says it dispatched air, navy and missile units to conduct joint live-fire drills around Taiwan to warn against what it calls separatist and “external interference” forces. Taiwan says it has placed its forces on alert. Monday's drills came after Beijing expressed anger at what could be the largest-ever U.S. arms sale to the self-ruled territory. It also expressed anger over a statement by Japan’s prime minister that its military could get involved. Taiwan’s aviation authority says more than 100,000 international air travelers will be affected by the drills that continue Tuesday. U.S. President Trump said he was not informed of the military exercise in advance but also suggested he didn't believe the Chinese leader would attack Taiwan.
