Iran and the six world powers may start drafting final agreement over Tehran's nuclear program in near future, Press TV quoted a senior Iranian nuclear negotiator as saying on Sunday. Abbas Araqchi expressed hope that the two sides would start drafting the text of final agreement next month, according to the report. "We hope that in the upcoming talks, we would be able to bring the views closer and narrow the differences regarding major issues, so we could get to the details and start writing the text," Araqchi was quoted as saying. The remarks by Araqchi follows a three-day nuclear meeting of experts from Iran and the P5+1 group, namely Britain, China, France, Russia, the United States plus Germany, concluded in Vienna on Saturday. After the talks, the head of Iranian negotiation team Hamid Baeidinejad said Saturday that "the useful technical talks helped the parties to understand each other's stance better." Iran and the P5+1 group held a two-day nuclear meeting in Vienna. Both EU Foreign Policy Chief Catherine Ashton and Iranian Foreign Minister Mohammad-Javad Zarif called the talks " substantive" and "useful." Both sides have agreed to reconvene the next round of high- level talks in Vienna on May 7, in which they will continue to discuss tough issues, including Iran's heavy water reactor.
