At a major security forum in Singapore, Shinjiro Koizumi defended Japan’s military buildup and cast China as the more opaque actor. The exchange reflects a deepening regional rift over Taiwan, security policy and the balance of power in Asia.
Japan and China are arguing about armies and safety. Japan’s defence minister said Japan is not becoming scary again, even though it is spending more on defence.
China says Japan is acting too tough. Japan says China is the one growing its military in ways that are not very open. It is a bit like two neighbours accusing each other of building a bigger fence first.
The argument matters because both countries are big, and what they do can affect many other countries nearby. A meeting in Singapore was supposed to help people talk things through, but the tension was still there.
Analysis
What happened
Japan’s defence minister, Shinjiro Koizumi, used the Shangri-La Dialogue in Singapore to reject China’s accusation that Tokyo is pursuing “new militarism.” He argued that Japan is not hiding anything about its military buildup and said the country’s past as a peaceful nation remains intact.
The dispute with China
The confrontation sits inside a wider diplomatic spat that has been growing since Japan’s prime minister, Sanae Takaichi, suggested in November that Japan could intervene militarily if China moved against Taiwan. Beijing has since accused Tokyo of taking a reckless security path that could unsettle the region. Koizumi said China is expanding its military power with too little transparency and that its activities are a serious concern for Japan.
Japan’s direction
Koizumi said Japan will keep building up its defence capabilities and keep updating them openly. He specifically pointed to artificial intelligence, uncrewed systems, and cyber and space defence as areas for continued investment. His message was that Japan sees its military changes as a response to an increasingly difficult security environment, not a return to wartime behaviour.
Regional context
The Shangri-La Dialogue is one of Asia’s main defence gatherings, bringing together officials and experts from roughly 45 countries. China’s lower-level delegation, without defence minister Dong Jun for a second year, underlined the distance between the two sides. Koizumi said he regretted not being able to meet Chinese counterparts at the summit.
