The Quadrilateral Security Dialogue, or Quad, gained momentum during this same crisis as the Covid-19 outbreak brought the world to a halt. Although it is a top priority for the Quad, opposing China now seems to be the main agenda due to the changing security landscape. That is to say, even if the Quad has not explicitly acknowledged this, China is unquestionably the major issue. The entire logic for the creation of the Quad is quantified by Beijing’s exclusion from the four-member grouping. In this situation, the Quad can be viewed as a novel type of security partnership for the twenty-first century.
