Araghchi said serious decisions need to be made in the capitals of the countries which are parties to the talks in order to resolve key outstanding issues.

“Today is the last day of the sixth round of talks, and we have gone through very difficult days. We are now in a situation where we think almost all the agreement documents are ready. The main issues of contention that remain, some issues have been resolved and some issues still remain, but it has taken a very precise form and it is quite clear what the dimensions of these disputes are,” Araghchi said.

Araqchi also said the negotiating teams are closer to reaching an agreement than ever.

He expressed hope a deal can be clinched in the upcoming round of negotiations but noted that it cannot be guaranteed.

The heads of other negotiating teams also confirmed the progress made in the talks, and highlighted the need for all sides to work, with a constructive approach, towards paving the way for reaching an agreement.
