Quick Summary

China's defense ministry has expressed concern over Japan's plans to arm submarine drones with long-range missiles and test hypersonic weapons in Australia. According to China's spokesman Zhang Xiaogang, these moves are a "dangerous" expansion of Japan's military arsenal that resembles its pre-World War II militarization. Japan's 2022 security strategy, which includes a "counterstrike capability," has led to a rapid expansion of the country's long-range strike capabilities. The key numbers mentioned in the article do not specify exact figures, but China views these developments as a challenge to its military interests.

Story summary

In recent days, Beijing has expressed concern over Japan's plans to arm submarine drones with long-range missiles and test hypersonic weapons in Australia. China's defense ministry spokesman Zhang Xiaogang said that these initiatives demonstrate Japan's "openly expanded military arsenal," which he claims has a "striking resemblance" to Japan's pre-World War II militarization. This criticism comes as part of Japan's broader effort to expand its long-range strike capabilities, including the adoption of a "counterstrike capability" in its 2022 security strategy. Under this policy, Tokyo aims to defend itself by striking military targets within an adversary's territory after an armed attack, while pre-emptive strikes remain prohibited. The Chinese government has not specified why these particular weapon programs pose challenges for China's military (PLA). Japan's moves have been seen as a significant development in the region, with implications that may affect the balance of power between Beijing and Tokyo.
