"There has been good progress on all four issues of removing sanctions, nuclear issues, verification and obtaining guarantees" Iran's foreign ministry spokesman Saeed Khatibzadeh told a Monday press conference. He cited "the result of the efforts made by all parties to reach a stable agreement".

"We are seeking a reliable and stable deal," Khatibzadeh said. "If the other party thinks an unstable and unreliable agreement is to their benefit, this is not what the Islamic Republic is after." On Sunday the Iranian foreign minister Hossein Amir-Abdollahian asserted that both sides are nearing a "good agreement", according to the AFP.

French Foreign Minister Jean-Yves Le Drian appears to be in agreement, having said days ago that talks are progressing on a "rather positive path". He said that momentum must be maintained toward a speedy resolution if a firm deal is to be reached.
