China Shadows Australian and Canadian Warships in Taiwan Strait, Raising Security and Social Stakes

China’s military has trailed Australian and Canadian warships transiting the Taiwan Strait, condemning the passage as a provocation and warning of heightened security risks. The Strait, which is seen by the United States, Canada, Australia, Britain and Taiwan as an international waterway, remains one of the most sensitive maritime corridors in the Indo-Pacific.

The Australian destroyer HMAS Brisbane and the Canadian frigate Ville de Québec sailed through the contested strait between 6 – 7 September. Both navies underscored their commitment to international law, particularly the UN Convention on the Law of the Sea, describing the transit as part of broader regional security deployments. Canada’s Operation Horizon and Australia’s Regional Presence Deployment are designed to reinforce freedom of navigation, counterbalance coercion, and stabilize maritime trade routes essential for global commerce.

Taiwan’s defence ministry reported closely monitoring the activity, emphasizing that it regularly deploys air and naval units to safeguard the strait’s security. The U.S. Navy and allied forces conduct similar passages roughly once a month, reinforcing a collective security framework across the Indo-Pacific.
