Namdar Zangeneh said that Total of France, Anglo-Dutch Shell, Italy's ENI, Norway's Statoil, Britain's BP and U.S. companies Exxon and Conoco would be welcome to invest in Iran, according to Reuters.
Speaking to reporters at the meeting of the Organization of the Petroleum Exporting Countries (OPEC), he said he was already in talks with some of companies, specifying that none were from the U.S.
