In a discussion with NDTV's Prannoy Roy, Sunil Mittal, CEO, Bharti Airtel said that it is a lot tougher to do business in India today because the environment is different. "We have gone out of India because we wanted to have a geographic diversification. We also had the capital and base to go out. However, we would like to reserve cash and wait for the right time to business here," he said.
