China's test firing of a nuclear-capable ballistic missile into the South Pacific on Monday has added to unease in the Pacific over military posturing and strategic alliances.
Regional governments were notified by China shortly before it launched the test, on the same day that Australia's prime minister Anthony Albanese went to Fiji to sign new treaties related to security and defence.
If the test launch was a clear message from China, the reaction from Australia and New Zealand has been swift.
Both governments accused China of undermining the peace and stability of the region, and of going against the values of Pacific Island countries as enshrined in the Pacific Forum's Ocean of Peace initiative.
'Please refrain'
The response from Pacific Island governments was generally more muted, although the biggest of the Island countries, Papua New Guinea, made an emphatic call against militarisation of the region.
PNG's Prime Minister James Marape made an "appeal to our Chinese friends that this be the last such missile test conducted in Pacific waters".
"This message is not directed only at China. It applies equally to the United States, France, Japan, the United Kingdom and every nation with military capability.
"If you respect the Pacific and its people, then please respect our ocean. We ask all major powers to refrain from using Pacific waters for missile testing, military weapons trials or any activity that contributes to conflict or militarisation," Marape said.
Restraint urged
The Solomon Islands prime minister, Matthew Wale, said China's actions were not the sort of thing a good friend to the Pacific Islands does, and described the missile test as being not good for the region.
Wale, who today hosted Albanese in Honiara, said that as chair of the Pacific Islands Forum he had registered a strong protest with China's ambassador, and that Solomon Islands also lodged a protest note.
He said the message against using missiles in the region applied to all other nations too.
Meanwhile, Fiji reaffirmed its commitment to the Treaty of Rarotonga which established the South Pacific Nuclear Free Zone, the intent of which, New Zealand pointed out, has been breached by China's test.
The Fiji Foreign Minister Sakiasi Ditoka urged restraint and underlined the need for peace, dialogue, transparency, mutual respect and adherence to international law.
"Fiji therefore encourages all states to exercise restraint, communicate openly, and conduct their activities in a manner that strengthens regional confidence and security rather than contributing to heightened tensions," he said.
Chinese foreign ministry spokesperson Mao Ning said the launch was consistent with international law and customary international practice and was not directed at any specific country or target.
Not just China
However the general secretary of the Pacific Council of Churches, Reverend James Bhagwan, said it was a reminder of how quickly the Pacific's Ocean of Peace can be turned into a theatre of power.
"At the same time, we are very mindful of the narrative which paints only China as an aggressor," he told RNZ Pacific.
"It must be noted that the United States of America annually fires four nuclear-capable Minuteman III intercontinental ballistic missiles into our Blue Pacific, targeting Kwajalein Atoll in the Marshall Islands."
Reverend Bhagwan said the Pacific region has had the most nuclear detonations of any region, at over 300, and that Pacific Islanders are firmly opposed to nuclear arms.
"That's why we were in the Australian parliament this past week to call on the Labor government to sign the treaty on the prohibition of nuclear weapons, noting that Prime Minister Albanese and many others in his party and in government and in parliament had pledged to do so eight years ago.
"We need Australia to lead the Pacific and secure our region from the threat of nuclear disaster by helping us take nuclear weapons off the table as an option," Bhagwan said.
But at this time of heightened competition for power in the Pacific, it appears the Australian Labor Party's promise of support for the ban on nuclear weapons may have been put on ice.
It comes as the new US ambassador to New Zealand, Samoa, the Cook Islands and Niue last week pressed Wellington to revisit its stance against hosting nuclear ships.
The Pacific's anti-nuclear resolve is being tested.
