External Affairs Minister S Jaishankar on Saturday dismissed China's vehement opposition to the Quad, saying the grouping will do "positive things" and contribute to the prosperity and stability of the strategic Indo-Pacific region and criticising it repeatedly will not make the four-nation grouping less credible. Jaishankar's remarks in response to a question came a day after he and other foreign ministers of Quad –US Secretary of State Antony Blinken, Japan’s Yoshimasa Hayashi and Australia's Marise Payne - on Friday vowed to expand cooperation to keep the Indo-Pacific free from "coercion".
