Iran and the 5+1 Powers resume high-level talks in Vienna on Tuesday.
The two sides are negotiating for a comprehensive nuclear agreement, following Novembers interim deal. They opened the comprehensive discussions last month in Vienna, and experts held technical talks in early March.
Under the six-month interim deal, which came into force on January 20, Iran is suspending its enrichment of uranium to 20% and diluting existing stock or converting it into fuel plates which cannot be used in a military program. The US and the European Union have begun lifting some sanctions, although most remain in place pending a comprehensive agreement.
The comprehensive deal will also seek agreement on the status of Irans nuclear facilities, such as the Fordoo enrichment plant and the Arak heavy-water nuclear reactor, and on a system of supervision and inspections.
The Iranian Government has the support of the Supreme Leader for the talks; however, it is under pressure from hardliners opposed both to negotiation with the Americans and to President Rouhanis declared intentions for cultural openness.
That tension spilled over on Monday night, when Zarif cancelled a working dinner with the European Unions Catherine Ashton, the lead negotiator for the 5+1 Powers.
Zarif was protesting Ashtons meeting in Tehran last week with womens right activists, an event which has fed hardline denunciations of Western support for sedition.
However, a more positive signal came from a discussion between the deputies to Zarif and Ashton. Abbas Araqchi and Helga Schmidagreed on an agendafor todays discussions, according to Iranian State media.
