"I have known (Anil) for many years. He just came to see me. I have nothing more to say," he told reporters when asked about the nearly 30 minute meeting.
Ambani also refused to speak to mediapersons about the meeting, where Oil Secretary S Sundareshan was also present.
Official sources had yesterday indicated that the government may allocate natural gas to Anil Ambani Group's proposed power plants like the Dadri project in Uttar Pradesh only six months prior to commissioning, as reservation of gas is not allowed under the present policy.
Last month, Anil Ambani group's Reliance Natural Resources plea for cheap gas from elder brother Mukesh-led Reliance Industries was turned down by the Supreme Court on the ground that gas was a national asset and government had the last word on its pricing and utilisation.
The Ambani brothers have since agreed to renegotiate an agreement on gas supply and Mukesh at the Annual General Meeting of Reliance Industries last week said his firm was ready to supply gas to Anil group's power plants, as and when they are ready.
