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, China's Defense Ministry spokesperson Zhang Xiaogang criticized Japan for expanding its military capabilities, specifically its plans to arm submarine drones with long-range missiles and test hypersonic weapons in Australia. This move is seen as a threat by the Chinese government, who claims it has a "striking resemblance" to Japan's militarization before World War II. The criticism comes after Japan adopted a new security strategy in 2022, which allows for counterstrike capabilities, including the ability to strike military targets in an adversary's territory for self-defense. This development is seen as a challenge to China's own military, known as the PLA (People's Liberation Army).
