China’s navy test-launched a long-range ballistic missile with a dummy warhead from a nuclear-powered submarine in the South Pacific on Monday. The launch drew immediate protests from Australia, Japan, and New Zealand, who cited concerns over regional stability and insufficient notification of the military activity.
How the South Pacific Nuclear Free Zone Treaty Applies
The launch occurred within the South Pacific Nuclear Free Zone, an area governed by the 1986 Treaty of Rarotonga. This treaty prohibits nuclear weapons throughout the region. China ratified the protocols of this treaty in 1987, which included a pledge not to test nuclear weapons within the zone or threaten signatories with territory in the region.
New Zealand officials stated they were informed of the test only hours before it took place.
“It appears that despite our long-standing concerns about this type of activity, China carried out the test within hours of informing us,”
Winston Peters, Foreign Minister of New Zealand
The timing of the launch coincided with a diplomatic shift in the region. On the same day as the test, Australia and Fiji signed a new mutual defense treaty designed to counter Chinese influence in the Pacific.
Australian and Pacific Island Reactions to the ICBM Test
Australian Prime Minister Anthony Albanese characterized the test as a risk to peace and stability. Speaking during a visit to the Solomon Islands, Albanese noted that the intercontinental ballistic missile (ICBM) was fired from a nuclear-powered submarine, a combination that increases the strategic stakes.
“Part of the concerns that we will express is the nature of the weapon that was tested that has a capacity clearly to reach at long range and to cause considerable, considerable damage were it to be weaponised.”
Anthony Albanese, Australian Prime Minister
The reaction extended to local Pacific leadership. Matthew Wale, leader of the Solomon Islands and chair of the Pacific Islands Forum, registered a strong protest with the Chinese ambassador. Wale stated that while China is a friend to the Solomon Islands, testing ICBMs in the region is not an act of friendship.
Australian cabinet minister Pat Conroy further disputed Beijing’s claims of legality. In an interview with ABC radio, Conroy rejected the notion that the launch complied with international law, specifically citing the Hague Convention on ballistic missile tests.
Security Concerns in Japan and the United States
Japan’s Defense Ministry urged Beijing to rethink its testing protocols to ensure projectiles do not fly over Japanese territory. Chief Cabinet Secretary Minoru Kihara linked the current tension to China’s increased military spending and activities around Japan.
“China’s military activities, combined with its lack of transparency, have become a grave concern for Japan and the international society,”
Minoru Kihara, Chief Cabinet Secretary of Japan
The U.S. State Department framed the launch as part of a broader, opaque nuclear buildup. Spokesperson Thomas Pigott argued that while the U.S. works to prevent nuclear proliferation, China is moving in the opposite direction. Pigott stated the U.S. will continue to push for a regularized notification arrangement for space and ICBM launches.
Beijing’s Defense of the “Routine” Training
The Chinese government has dismissed the international outcry as an overreaction. A spokesperson for the Ministry of Foreign Affairs and Mao Ning both maintained that the launch was a safe, professional part of annual military training.
Beijing’s official position is summarized in the following claims:
- The launch complied with international law and practice.
- Relevant countries were notified in advance.
- The missile was not directed at any specific country or target.
- Critics should avoid “overinterpretation” of the event.
This test follows a pattern of increasing naval assertions. China’s last Pacific missile test occurred two years ago, which was the first such test since 1980.
Strategic Implications for the Pacific
The shift from land-based to submarine-launched ICBM tests signals a change in China’s nuclear deterrent strategy. By utilizing nuclear-powered submarines, China increases the survivability and reach of its strategic arsenal.
The friction between the “routine training” narrative and the “destabilizing event” narrative highlights a deepening divide in the Pacific. While Beijing views these tests as a standard assertion of superpower status, regional actors see them as a violation of the spirit, if not the letter, of the Treaty of Rarotonga.
The immediate fallout suggests a tightening of security pacts. The launch occurred as Australia secured more defense deals with Pacific Island nations, a trend The Wire China notes is happening as Australia pushes back against Chinese influence.
