China criticizes Japan's hypersonic weapons

China's defense ministry spokesman Zhang Xiaogang criticized Japan's military initiatives on Thursday. He said Japan had "openly expanded its military arsenal" by planning to arm submarine drones with long-range missiles and test hypersonic weapons in Australia.

Zhang described these moves as "dangerous." He claimed they bore a "striking resemblance" to Japan's pre-World War II militarization. The spokesman did not detail why these specific weapon programs could challenge China's People's Liberation Army.

Japan has rapidly built up its long-range strike abilities. This follows the adoption of a "counterstrike capability" in its 2022 national security strategy.

The policy allows Japan to strike military targets in an adversary's territory for self-defense. This is permitted only after an armed attack occurs. Pre-emptive strikes remain forbidden under the strategy.

Hypersonic Weapon Development

Japan is testing hypersonic weapons in Australia. These weapons can travel at speeds exceeding Mach 5. They are difficult to intercept with current missile defense systems. This development is part of a broader military modernization, detailed in our stats on regional capabilities, as Japan aims to enhance its deterrence.

Underwater Drone Arsenal

Another initiative involves arming unmanned underwater vehicles with long-range missiles. These submarine drones could operate covertly. They would add a new layer to Japan's maritime strike capabilities, potentially affecting the regional balance reflected in our standings.

The combination of hypersonic speed and underwater launch platforms represents a significant shift. It extends the potential reach of Japanese forces.

Regional Security Context

China's public criticism highlights regional tensions. Military developments by one nation often prompt reactions from neighbors. Japan's post-war constitution historically limited its military to self-defense.

The 2022 strategy marks a notable change. It explicitly prepares for strikes against enemy bases.

Zhang's comments directly link current plans to Japan's wartime past. This historical framing is a common feature in diplomatic disputes between the two countries. The accusation of militarization is a serious one in East Asian relations.

Policy and Prohibition

Japan's government maintains its actions are defensive. Officials stress that any counterstrike would be a response to an attack. The prohibition on pre-emptive action is a key legal and political constraint.

The definition of what constitutes an "armed attack" triggering a response remains a subject of analysis. Security experts watch how these policies are interpreted.

China's defense ministry chose to highlight these two weapon programs. The statement was delivered at a regular press briefing. It serves as official, on-record concern from Beijing.

Japan's military expansion continues amid a complex security landscape. The developments are watched closely by multiple nations in the Indo-Pacific. Zhang Xiaogang's remarks provide a clear window into one major neighbor's apprehensions.
