A new round of nuclear talks among Iran the P5+1 grouping is set to get underway today in Vienna.
The negotiations are expected to focus on a final agreement to limit Iran's ability to produce nuclear weapons before a July 20th deadline.
July 20th is when an interim agreement hammered out by the two sides late last year expires.
Iranian Foreign Minister Mohammad Javad Zarif says his country is determined to reach a new agreement.
"Now we should start negotiating and drafting text of the final agreement. Well it is a difficult stage. At the beginning of the talks in Vienna we planned several meetings for this purpose. There are still three rounds of talks excluding this round, so I am hopeful. We have come here with unflinching determination to reach a result, to reach an agreement, while protecting the rights of the Iranian people."
Under the temporary deal in November, Tehran agreed to cap its nuclear activities in return for an easing of sanctions.
World powers have long-been concerned Tehran's real aim is to produce nuclear weapons.
Iran has consistently denied the charge, insisting its nuclear program is for civil use only.
Iranian authorities recently agreed to give UN inspectors more access to their nuclear sites.
