- China's PLA Navy launched a submarine-launched ballistic missile on Monday that flew roughly 7,000 km southeast over the Pacific and splashed down near Nauru and Tuvalu, both signatories to the South Pacific Nuclear Weapons Free Zone established by the 1986 Treaty of Rarotonga.
- New Zealand's foreign minister said the test 'goes against the object and intent' of the Rarotonga treaty, and Australia publicly raised similar concerns, arguing that even though a dummy warhead meant no technical breach, the spirit of the zone was violated.
- China's Foreign Ministry spokesperson Mao Ning called the launch 'conducted safely, systematically, and professionally' and urged other countries not to 'over-interpret it,' noting Beijing gave several hours of advance notice to key regional governments.
- Olamide Samuel of the Open Nuclear Network said the test fits a 'growing trend' of nuclear-armed states pressuring nuclear-weapons-free zones, citing the U.S. pressuring the U.K. over Diego Garcia and Russia pushing Kazakhstan to allow missile testing.
- China has repeatedly criticized the AUKUS nuclear-submarine deal — under which Australia will receive up to eight nuclear submarines — as a Rarotonga violation, creating an irony flagged by analysts who note Beijing's simultaneous public support for nuclear-weapons-free zones.
- The U.S. conducted a comparable ballistic missile test in March, but its missile splashed down in Pacific waters not covered by any NWFZ treaty, a distinction Samuel cited as evidence of a 'slow spiral' toward bare-minimum treaty compliance.
Why it matters: The test marks the second Chinese ballistic missile fired into the Pacific in under a year (the prior one was September 2024), and analysts warn the combination of Chinese, Russian, and U.S. pressure could erode aspirational norms around the world's five nuclear-weapons-free zones, affecting 13 Pacific island states party to Rarotonga alone.
