Earlier this week, India formally invited Australia to join the large-scale naval exercises to be conducted in the Bay of Bengal (3-6 November) and the Arabian Sea (17-20 November), involving in addition to the navies of India and Australia naval assets of the US and Japan.
This is a very significant development—if not militarily, certainly symbolically—for the future of peace and security in the Indo-Pacific. This will be the first time that the navies of the four countries will be participating together in naval exercises.
Australia, India, Japan and the US are members of the Quadrilateral Security Dialogue, better known as the Quad—a grouping of four Indo-Pacific democracies founded in 2007 whose main mission is to ensure a Free and Open Indo-Pacific primarily through the maintenance of the rules-based international order.
