India was initially hesitant to participate in U.S.-led initiatives that could be perceived as containing China’s influence in the Indo-Pacific. However, border disputes with China led to India becoming an active member of the Quadrilateral Security Dialogue (Quad) in 2017. Another standoff in the Himalayas between India and China in June 2020 helped further deepen New Delhi’s engagement with the Quad. Given these past drivers of India’s diplomatic and security cooperation with the Quad, developments in Sino-Indian relations will likely continue to shape the country’s future participation in the Quad. President Joe Biden’s ongoing push to strengthen relations between members of this strategic dialogue has recently prompted Beijing to resolve tensions with New Delhi. In this environment, India may also increasingly see its participation in the Quad as a source of leverage for the country.
