Britain’s new defence pact with the United States and Australia has been hailed as a landmark moment in the West’s strategic engagement with China in the Indo-Pacific region.

As part of the deal, Australia will be allowed to build nuclear-powered submarines for the first time using technology provided by the US and the UK.
