China test fires submarine-launched missile in Pacific, rattling neighbors

China fired a long-range ballistic missile from a nuclear-powered submarine into the Pacific on Monday, a rare launch that put regional security politics on display as Pacific governments weighed Beijing’s reach. Xinhua said the missile carried a dummy warhead and landed in “designated waters” at 12:01 p.m. local time, or 0401 GMT, and described the launch as a “routine arrangement” in China’s annual military training.

The test carried a broader message than the missile itself. A submarine launch from deep in the Pacific signals that China is willing to demonstrate long-range military capability far beyond its coastline, forcing neighbors to account for a People’s Liberation Army Navy that can move nuclear-powered platforms across a vast maritime theater. The exact location of the launch was not disclosed, leaving surrounding governments to judge the significance of the test without knowing precisely where the submarine operated.

Japan, Australia and New Zealand moved quickly to criticize the launch or express concern. Australia said the test was destabilising to the region, while New Zealand and Australia said it threatened peace and stability in the Pacific. Japan said its embassy in Beijing had been informed in advance by Chinese authorities and strongly urged Beijing to reconsider so the launch would not pose a threat to Japanese security.

The timing sharpened the diplomatic contrast across the South Pacific. The missile test came on the same day Australia and Fiji signed a mutual defence pact in Suva, Fiji’s capital, in a move designed to deepen Canberra’s Pacific security posture and counter Beijing’s influence in the region. It was Fiji’s first mutual defence treaty and Australia’s fourth, following its 1951 treaties with the United States and New Zealand and a bilateral treaty with Papua New Guinea signed last year.

The Australia-Fiji package also included the Vuvale Union economic agreement, under which Australia will invest more than A$1 billion, about US$693 million, in Fiji over 10 years. Together, the missile launch and the new pact underscored a Pacific security environment in which military signaling and alliance-building now move in lockstep.
