Chairman of Bharti Airtel, Sunil Mittal, on Monday, said it has so far invested $4 billion into the Nigerian economy since the company began operations in the country.
“We are already investing about $400 million a year in Nigeria, which has been going on for the last many years, and that will continue. That is business as usual. We have invested just under $4 billion since the time we came into Nigeria,” he said.
