Citigroup Inc., the New York-based bank that sold its 20 percent stake in a Saudi Arabian lender six years ago, is applying to open an office in the Kingdom, shareholder Prince Alwaleed Bin Talal said. “Saudi Arabia welcomes the presence of a Citibank office here, Alwaleed, who owned 218 million shares in the bank as of November 2008, said on Tuesday in an interview with Bloomberg Television. The bank sold its 20 percent stake in the Saudi American Bank, now known as Samba Financial Group, to the state Public Investment Fund for $760 million in 2004, ending a business that started in 1955. A 2003 capital market law opened the door for foreign banks to apply for licenses.
