Nahavandian made the remarks in a meeting in London with Anthony Browne, chief executive of the British Bankers' Association.
Announcement of the 'Implementation Day' for the July 14 landmark nuclear deal between Iran and the six world powers as well as lifting the anti-Iran sanctions afterward have made it possible now for the world to resume its economic interaction with Iran, Nahavandian said.
He said that there is a bright prospect for economic cooperation with Iran based on a trade guidelines set in the Joint Comprehensive Plan of Action (JCPOA) for having transparent ties with Iran.
Noting that Iran has made certain economic plans for its interaction with the world banks, the official said such plans have been activated after lifting of the sanctions in January.
Meanwhile, the British official expressed satisfaction over removal of anti-Iran sanctions saying the UK banks are interested in cooperating with Iran.
Nahavandian is in London for an economic conference themed 'Iran's Economic Opportunities and Challenges.'
