Chinese Foreign Minister Wang Yi says Japan has "crossed a red line” with comments by the country's new leader suggesting a potential military intervention over Taiwan

Japan plans to deploy medium-range surface-to-air missiles on Yonaguni – making it a frontline of defence in the event of a Chinese attack on Taiwan – as part of its broader military build-up across the southern island chain.

The remarks come amid the two countries’ worst diplomatic crisis in years, after the Japanese prime minister said a Chinese attack on Taiwan could trigger a military response from Tokyo.

With Japan’s new leader refusing to back down from China’s show of force and claims on Taiwan, Xi Jinping picks up the phone to try to pry the U.S.-Japan alliance apart.

Japan’s defense minister, visiting a military base close to Taiwan, said plans to deploy missiles to the post were on track as tensions smolder between Tokyo and Beijing over the East Asian island.

Japan’s Prime Minister Sanae Takaichi, who recently triggered China’s fury with a comment suggesting a Chinese move against Taiwan could prompt a Japanese military response, said Tuesday that she received a call from U.

China slammed Japanese Prime Minister Sanae Takaichi’s comments suggesting potential Japanese military action over Taiwan as reckless and shocking, calling it a “grave violation” of international law and threatening a military response against any “aggression”.
