China’s defence ministry said at the time that the test was a “legitimate and routine arrangement for military training”, in line with international law and not aimed at any country or target.An image released by the Chinese military showing the launch on September 25, 2024 of an intercontinental ballistic missile carrying a dummy warhead.People’s Liberation ArmyAustralian Strategic Policy Institute executive director Justin Bassi said the Chinese test-firing “represents an escalation in its ongoing military expansion and sends a deeply concerning strategic signal to Australia and the wider Indo-Pacific”.The Chinese navy conducted live-firing exercises in the Tasman Sea in February 2025, forcing commercial airlines to change their flight routes.More to comeFrom our partners
