S Jaishankar, in an exclusive conversation with NDTV's Editor-in-Chief Sanjay Pugalia, outlined India's responsibily as the G20 chair. "Other countries today are watching us. Why 125 countries were so committed to talking to us? They feel India understands the problems of the developing world. We never had a G20 chair before to understand their problems. This is our credibility today," he said.
