An Iranian deputy foreign minister

 An Iranian deputy foreign minister voiced satisfaction in the progressive trend of the nuclear talks between Iran and the six major world powers, and described the one-on-one talks with the Sextet members as a productive plan to narrow down differences before the scheduled high-level meeting in September.

“Iran will definitely hold bilateral talks with the Group5+1 (the US, Britain, France, Russia and China plus Germany) ahead of the scheduled (high-level) meeting between (Iranian Foreign Minister Mohammad Javad) Zarif and (EU Foreign Policy Chief) Catherine Ashton on the sidelines of the (annual gathering of the) UN General Assembly,” Deputy Foreign Minister for European and Americas' Affairs Majid Takht Ravanchi said on Saturday.
“The exact timetable and venue of the meetings have not been determined yet,” he added.
Last month, Iran and the G5+1 had over two weeks of negotiations in Vienna with no final agreement between the two sides, but they extended their July 20 deadline for a few more months.
During the talks, a senior member of the Iranian team of negotiators stressed that the excessive demands made by the other side are the root cause of the differences between Tehran and the world powers.
At the end of their talks, the two sides agreed to extend the talks till November 24 for brokering a final deal.
Zarif and Ashton in a joint statement after over two weeks of talks stressed the need for more efforts and time to reach an agreement with the world powers over Tehran's nuclear program.
Due to certain differences over some fundamental issues the two sides agreed to extend the Joint Plan of Action by November 24, they added.
