Kaifu Sanae breaks through the Abe Cabinet's position.

Kawamura Noriyuki, honorary professor at the Nagoya University of Foreign Studies and vice president of the Japan-China Relations Society, said in an interview on the 14th that in the parliamentary debate, Koichi Hagiuda defined the so-called "Taiwan contingency" as a situation where the right to exercise collective self-defense can be used in the face of a "threat to survival," which is equivalent to giving China a "warning" of war. Kawamura Noriyuki stated that the cabinets of Japan have never recognized the exercise of collective self-defense based on the principle of "exclusive defense" stipulated by the peace constitution. The Abe Shinzo cabinet in 2015 forcibly passed the security legislation allowing for the exercise of collective self-defense in parliament, but the law was criticized by opposition parties and scholars for violating the constitution. Subsequent prime ministers including Shinzo Abe, Yoshihide Suga, Fumio Kishida, and Shigeru Ishiba all remained vague on what constitutes a "threat to survival." Hagiuda's statement broke through the position of previous cabinets, severely interfering in China's internal affairs and trampling on the One-China principle.
