Bank of Namibia spokesperson Ndangi Katoma said the bank had granted provisional authorisation to Bank BIC Namibia Limited to conduct business as a banking institution in Namibia.
Bank BIC Namibia Limited is a subsidiary of Angolan Bank Banco BIC, which is 42.5-percent owned by Africa's first woman billionaire, the daughter of Angolan President Jose Eduardo dos Santos.
Isabel dos Santos, is reported by Forbes to be worth USD 3 billion.
But Katoma warned that Bank BIC Namibia would not be allowed to engage in banking activities with any person in Namibia just yet, "especially soliciting deposits."
