2025–2026 China–Japan diplomatic crisis

Relations between China and Japan entered a state of crisis in November 2025, after Japanese prime minister Sanae Takaichi said in the Japanese parliament that a Chinese attack on Taiwan could potentially constitute an "existential crisis for Japan" under the Legislation for Peace and Security, allowing Japan to take military action in collective self-defence. Following these remarks, the Chinese consul general in Osaka, Xue Jian, made threatening comments against Takaichi on X (formerly Twitter), triggering a diplomatic row between the countries.
