Japan has granted the United States permission to deploy medium-range Typhoon missiles during joint military exercises next month, prompting warnings from Russia and China. Both nations describe the move as a threat to regional stability. Russia calls it a direct strategic risk and warns of potential military responses, while China urges Japan to pursue peaceful development and caution. The Typhoon system, previously tested in the Philippines, will be stationed at Iwakuni airbase, but its actual use in upcoming exercises remains unclear.
