Deputy Foreign Minister in Legal and International Affairs Seyyed Abbas Araqchi said that although the Montreux talks have been constructive, there are differences to resolve.
He added meanwhile that "both sides at the moment have a better understanding of the issue.”
The senior diplomat added that a political decision would be made after discussing the technical issues as "sometimes technical talks offer technical solutions which help the process of political decision-making.”
"However, the more difficult decision is to be made by the other side and it is whether to continue imposing sanctions or to look for an agreement,” he added.
Araqchi further said that Iran’s principle in talks is to remove all sanctions.
"Although there exist some prominent political and legal sanctions, we are working on all kinds.”
Araghchi, pointing to the 4-day intense negotiations in Montreux, stated: "we did more progress this time, and both sides are now aware of the differences and all details. However, still we have a long way to go.”
