Chief negotiator of the Iranian delegation Abbas Araqchi said on Tuesday that Iran sought explanations from the US on regulating banking ties with Iran.
P5+1 have no identical understanding of the issue and each country expresses its own views, he said.
Some believe that the US Treasury Department has created an ambiguous situation and avoids to shed light on the issue for the companies willing to do business with Iran, he said.
Explanations should help remove existing doubts and ambiguities in broadening economic and banking cooperation with Iran, he said.
The current meetings give all sides a good opportunity to mull removal of hurdles on the way of sound implementation of the Joint Comprehensive Plan of Action (JCPOA), Araqchi said.
The Iranian agenda is to do its best to remove all concerns in reestablishing economic and banking cooperation with the outside world.
