China test-fired a long-range ballistic missile carrying a dummy warhead from a nuclear-powered submarine into the South Pacific on Monday, and by evening Australia, New Zealand and Japan had all protested.

The launch came at 12:01pm Beijing time, 2:01pm on Australia's east coast, according to Al Jazeera's account of the Chinese announcement. The missile came down in international waters, though reports of exactly where differ: AAP said it landed between Nauru and Tuvalu, while SBS placed the splashdown near French Polynesia. Through the state agency Xinhua, China called the launch a "routine arrangement" of its annual military training, "not directed against any specific country or target", and said relevant countries were notified in advance.

How much notice, and how useful, is its own dispute. Foreign Minister Penny Wong said Canberra had put its objection to Beijing directly. "Australia has been clear with China that we regard this as destabilising to the region," she said. "Australia has been clear that this proposed test is in the context of a rapid military build-up by China, which is lacking in the transparency and reassurance as to intent that the region expects."

New Zealand's foreign minister Winston Peters said the warning was measured in hours. "It appears that, despite our long-standing concerns about this type of activity, China carried out the test within hours of informing us," he said, adding that New Zealand and its Pacific neighbours had "no interest in China using the South Pacific as a testing site for missile capability".

Japan expressed "grave concern over the Chinese military's increased activity", urged Beijing to reconsider, and notified its coastguard of potential debris zones. The US State Department urged China to "engage in meaningful arms control discussions".

China last fired a missile of this range into the Pacific in September 2024, when the PLA Rocket Force sent an intercontinental ballistic missile with a dummy warhead into waters about 700 kilometres from French Polynesia's exclusive economic zone, its first such test over the Pacific since 1980. Monday's launch, by contrast, came from a strategic nuclear-powered submarine.

The test landed in the middle of Australia's Pacific week. Hours earlier in Suva, Anthony Albanese and Fiji's Prime Minister Sitiveni Rabuka had signed the Ocean of Peace Alliance, a mutual defence treaty backed by more than $1 billion over a decade. Rabuka said the pact was not aimed at Beijing. "It does not threaten Fiji's relationship with China nor Australia's relationship with China," he said.

By Tuesday, Beijing's position had not moved: routine training, notified in advance, directed at no one. The answer from the region, delivered in three capitals inside a day, was that none of that made it welcome.
