Qatar plans to be an active investor in Bharti Airtel
"QFE (Qatar Foundation Endowment) will be taking a board seat and this shows that on this one they'll be active investors and will have a say on the company's future," the source said.
"Qatar is in for the very long term," the person added.
Through its various holding companies, Qatar owns stakes in a variety of companies but rarely plays a publicly active role. Last year, it surprised investors by forcing Glencore to raise its takeover offer for Xstrata.
