China Summons Japanese Ambassador Over Prime Minister's Taiwan Comments

China has summoned Japan’s ambassador following comments by Japanese Prime Minister Sanae Takaichi, who suggested that Japan might intervene militarily to defend Taiwan. Beijing called the remarks “extremely dangerous” and demanded a retraction, warning that Japan would face consequences if it did not alter its position.

Why it matters:

China’s Vice Foreign Minister, Sun Weidong, summoned Kenji Kanasugi, Japan’s Ambassador to China, on Thursday to lodge a strong protest against Takaichi’s comments on Taiwan. The incident highlights rising tensions in the Asia-Pacific and signals Beijing’s sensitivity to statements it sees as challenging its territorial claims. While the immediate focus is diplomatic, the underlying issue involves regional security, international law, and broader geopolitical dynamics.

The big picture:

Japan’s 2015 law on collective self-defense allows military action only if the country’s survival is threatened.  Takaichi’s recent statements outlined a scenario under which Japan might consider intervention.  Although she did not directly target China, her remarks raised concerns, as Taiwan is considered a “red line” by Beijing, which views the island as part of its territory and has not ruled out the use of force. In response, China condemned her comments as “provocative. ” A spokesperson for China’s Foreign Ministry, Lin Jian, reminded Japan of its history of invasions justified under the pretext of national survival and warned that any Japanese military action in the Taiwan Strait would trigger a strong response.

What he’s saying:

Sun Weidong told Kanasugi that “the nature and impact of these remarks are extremely dangerous” and criticized Takaichi for refusing to retract them despite China’s objections.

On Friday, Japan’s Chief Cabinet Secretary Minoru Kihara told reporters:

“Peace and stability in the Taiwan Strait are crucial not only for Japan’s security but also for the stability of the international community. The government hopes to reach a peaceful solution to issues surrounding Taiwan through dialogue. Our stance remains unchanged and consistent with the Japan-China Joint Communiqué of 1972.” The 1972 Joint Communiqué normalized bilateral relations and recognized Beijing’s “One China” policy.

Also, Japanese officials, while defending the Prime Minister’s comments, emphasized that “peace and stability in the Taiwan Strait are important not only for Japan’s security but also for the stability of the international community.”
