VIENNA - Iran's financial sector offers opportunities for cooperation between domestic banks and foreign investors, Iranian central bank deputy governor Akbar Komijani said on Thursday. 'Iran is enjoying a very vastly developed banking sector ... there is plenty of room for cooperation, with joint ventures between foreign investors and Iranian partners,' Komijani said at a conference promoting trade between the European Union and Iran. 'E-banking has grown very much, but there is still a good opportunity to start business together in that area,' he added.
