The nuclear-capable missile that China test-fired from a submarine yesterday flew over multiple Pacific nations and appears to have hit waters close to Tuvalu's Exclusive Economic Zone (EEZ).China had called the launch "routine", but both Australia and New Zealand sharply criticised the missile test and labelled it "destabilising".Overnight, the head of Taiwan's national security council, Joseph Wu, posted an image on social media showing the missile arcing across Micronesia and Melanesia, before plunging into the ocean roughly 1,000 kilometres north-east of Solomon Islands.Mr Wu, who has long been a vocal critic of China, called the test "a provocation that destabilises the Indo-Pacific"."China just proved itself again to be a bully on the block," he said.Some Pacific officials have also expressed unease about the test to the ABC, but so far no Pacific nations have issued any public statements criticising Beijing's actions.The ABC has been told the missile, which was armed with a dummy warhead, flew over the EEZs of at least three Pacific island states, including the Federated States of Micronesia, Nauru and Kiribati.It landed closest to the EEZs of the Pacific nations of Tuvalu and Kiribati, about 1,000km north-east of Solomon Islands, and seems to have hit the water near the border of Tuvalu's EEZ, or potentially even just inside it.The trajectory of a test-fired Chinese ballistic missile in the Pacific, according to the Taiwanese government.
