Japan and China are locked in a diplomatic row after Prime Minister Sanae Takaichi said a potential Chinese attack on Taiwan could pose a “survival-threatening situation” for Japan. The remark, based on a 2015 security law, marked a rare public reference to Taiwan in Japan’s defence debate. Beijing called the statement “wrongful and dangerous” and lodged a formal protest. The Chinese Consul General in Osaka also posted a threatening message on X, later deleted, drawing condemnation from Tokyo. Taiwan criticised Beijing’s “wolf warrior diplomacy,” while the United States called the post a threat. The dispute has strained Japan–China relations further.
