The first formal summit of the heads of state of the four-member group of nations known as the `Quadrilateral Security Dialogue’ (Quad) (India, the US, Japan & Australia) is a significant development. In the US, the transfer of power to the Biden administration has only increased commitment to reviving the Quad. At a separate briefing in the US, the State Department spokesperson Ned Price has said that “maritime security is, of course, an important one, but our shared interests go well beyond that”.
