At the recent Shangri-La Dialogue, Defense Minister Shinjiro Koizumi delivered a blunt rebuttal to Meng Xiangqing, a professor at China’s PLA National Defense University. Meng had used his platform to sharply lambast Prime Minister Sanae Takaichi’s administration, accusing Tokyo of resurrecting a “new type of militarism.” Koizumi countered forcefully, stating that the true source of anxiety in the Indo-Pacific is China itself, pointing to Beijing’s expanding nuclear arsenal and unprecedented military build-up.

Noting the absence of China’s defense minister, Koizumi called for bilateral security talks, directly confronting a coordinated effort by the Chinese delegation to isolate Tokyo.

On the surface, the forum was a diplomatic victory for Japan. Philippine Defense Secretary Gilberto Teodoro backed Koizumi, while officials from the U.S., Australia, Vietnam, the U.K., France and Germany voiced shared concerns over China’s coercive policies. In Japan, public opinion took immense satisfaction in seeing Koizumi secure such broad international solidarity, leaving the Chinese delegation isolated. Yet, beneath this veneer of triumph lies a dangerous, carefully laid pitfall.
