China’s missile test reveals fragile state of world nuclear governance

China’s missile test reveals fragile state of world nuclear governance The reactions to Beijing’s ‘routine’ exercise put into focus a nuclear order that is rapidly fluctuating from Tehran to Tokyo The regional reaction was immediate, with Australia, Japan, the United States and Pacific nations raising concerns around insufficient notification and the politics of nuclear-free zones. Those reactions matter because they show how far nuclear politics has moved beyond the arsenals of large powers. The test was read through several lenses: evidence of Beijing’s maturing second-strike capability, a challenge to US allies and partners, a problem for Pacific nuclear-free norms, and a signal to states already reassessing nuclear weapons policy. The test revealed a nuclear order in motion. That order is increasingly shaped by three tracks. The first is Sino-Russian strategic alignment. The second is a US-led system of extended deterrence. The third is a diverse middle layer of secondary nuclear powers, nuclear-threshold states and “umbrella-anxious” allies. The first two tracks are hardening. The third remains fluid. For China and Russia, arms control cannot be reduced to counting deployed warheads while leaving US alliances, precision-strike networks, missile defences and foreign bases outside the discussion.
