Chinese jets swarm Taiwan: This week, multiple Chinese warplanes penetrated Taiwan's airspace. While Beijing does this quite often to flex its muscles, this time the jets took a different route, and one even got close to the Japanese island of Yonaguni, located less than 70 miles (113 kilometers) north of Taiwan. The maneuvers have been interpreted by experts as a direct warning from the Chinese to Japan not to overplay its hand. (It's worth noting that Tokyo could get dragged into a US conflict with China over Taiwan because, like Taiwan, it has a mutual defense treaty with the US.) More broadly, the flight patterns also indicate that China could surround Taiwan on three sides in an eventual invasion, cutting off the territory from US and Japanese military support. All this comes as the Biden administration has expressed serious concern (paywall) that Beijing is indeed planning to invade Taiwan in the very near term. With US-China relations getting hot, more rumblings over an invasion of Taiwan will surely turn the temperature even higher.
