NEW DELHI: A billion is not a small number — which is why the Economic Times Global Business Summit 2016 is a special gathering. Over two days — January 29-30 — in New Delhi, the summit will witness an eclectic gathering of global leaders of multi-billion-dollar businesses, political leaders who shape the destiny of more than a billion Indians, and thought leaders who shape the world view of the elite across the globe. In short, it will be Davos redux on Indian soil.
