Abbas Araqchi, deputy foreign minister for legal and international affairs, said addition of the ministerial-level officials could be necessary because some topics will require political decisions, the Tasnim news agency reported Monday.
Negotiations to put into practice an agreement on Iran's nuclear program signed in November ended Sunday in Geneva. Western nations involved in the talks with Iranian officials included representatives from the United States, China, Russia, France, Britain and Germany.
The Western delegations included technical experts from the six countries, while the Iranian team included nuclear experts and experts on banking, transportation and oil sanctions.
The next round of talks is expected to be led by Araqchi and Helga Maria Schmid, the European Union's deputy secretary general for political affairs of the European External Action Service.
