Indian government approved Brookfield asset management Inc.’s proposal to acquire  a 252 billion rupees ($3.4) stake in a trust that manages the wireless infrastructure of the nation’s biggest mobile phone service provider, people with knowledge of the matter said.

The telecom ministry permitted Brookfield to take control of Reliance Jio Infrated pvt. through Tower Infrastructure trust, the people said, asking not to be identified before a public announcement. The proposal was clearly by the finance and home ministries as well as the central bank in July, the people said.

The endorsement from the government -about a year after it was proposed- will help Asia’s richest man Mukesh Ambani add to the more than $20 billion he has raised by selling stakes in his technology venture, Jio Platforms Ltd.

The finance minister spokesperson could not reached on his mobile phone, while representatives for the communications ministry, home ministry and central bank didn’t immediately responded to queries seeking comment. A spokesman for Reliance declined to comment.

Ambani had planned to use the proceeds to repay “existing financial liabilities” and acquire stake his flagship Reliance industries Ltd. doesn’t own in Reliance Jio Infratel, according to a statement in July last year.
