President Hassan Rouhani's chief of staff says the Islamic Republic's policies on various issues, including nuclear energy, are "transparent", emphasizing that there should be no concerns over Iran's peaceful nuclear program.
Mohammad Nahavandian made the remarks in a meeting with the new Norwegian ambassador to Tehran, Aud Lise Norheim, on Saturday, ISNA reported.
He said nuclear negotiations between Iran and the major powers cannot "continue forever", urging the European Union to play a more active role to help the talks reach a conclusion in the specified time.
Iran and the major powers last month set a new deadline of June 30 to work out a comprehensive nuclear deal to resolve the 12-year dispute over Tehran's nuclear work.
Elsewhere, Nahavandian said the Islamic Republic's foreign policy is aimed at expansion of relations with the world's countries based on the principle of "mutual respect".
In addition, he pointed to the enormous potential for investment in Iran and said Tehran welcomes the "presence, cooperation and investment" of EU members in economic and cultural sectors of the country.
He said the two countries' private companies can collaborate in various economic areas, including oil and gas and fishing, adding that Iran and Norway can work together on research and scientific projects.
The Norwegian envoy, for her part, said the European country's companies are keen to have presence in Iran and expressed hope that she would be able to take steps during her mission to pave the way for expansion of relations between the two countries.
