The board of Birmingham International Holdings Limited has revealed Birmingham City are in talks with two different parties about the possible sale of the club.
The parent company of the Championship outfit have confirmed the interest to the Hong Kong Stock Exchange.
They said in a statement: "The company has been approached by two prospective buyers to explore the possibility of buying Birmingham City FC."
Although the Blues are not officially up for sale, chief executive Peter Pannu announced earlier this year that City were keen for new investment, while club president Carson Yeung is awaiting trial following allegations of money-laundering.
The two unnamed parties have entered into confidentiality agreements with the club.
Reports have suggested that former QPR chairman Gianni Paladini is in pole position to buy the club.
