Iran voiced satisfaction with the latest round of nuclear talks, with Foreign Minister Mhamamd Javad Zarif said they were "very serious and more positive than expected. 

Meanwhile, EU Foreign Policy Chief Catherin Ashton, who represents world powers in the talks, is to visit the Islamic Republic on March 9 and 10 ahead of the next round.

Speaking to reporters after the talks in Vienna Thursday, Zarif said that the two parts “agreed that no one 'surprises' the other side with new claims.”

The interim agreement gave the sides one year to finalize a comprehensive deal, Zarif said, but added that they were "trying to wrap up that in six months."

The top Iranian diplomat also announced that he and Ashton agreed to meet once a month by June to discuss the issues related to the talks between Tehran and the world powers.

“We agreed to hold several meetings at the level of Ms. Ashton and me every four weeks by (the Iranian month of) Khordad (May-June) and have working meetings between our experts on different issues which are on the agenda,” Zarif wrote on his Facebook page on Wednesday.

Meanwhile, a Western diplomat said on Thursday that Ashton is to travel to Tehran on March 9-10, ahead of the next round of talks planned for March 17.
For her part, Ashton described the talks as “productive and a good start”.

"We have had three very productive days during which we have identified all of the issues we need to address in reaching a comprehensive and final agreement," Ashton told reporters in a brief press conference with Zarif.

"There is a lot to do. It won't be easy but we have made a good start."
