TEHRAN, April 3 (Xinhua) -- The expert-level nuclear talks that started in Vienna on Thursday aimed at discussing a number of technical issues, Iran's official IRNA news agency reported.
In the meeting in Vienna, mainly technical issues, including Iran's Arak heavy water reactor, will be discussed, Iranian negotiator Abbass Araqchi was quoted as saying.
Also, talks on uranium enrichment and relevant issues will continue until the two sides reach a final understanding, he said.
Experts of Iran and six major world powers met on Thursday to prepare the ground for a comprehensive accord.
The Western countries asked Iran to significantly scale back its nuclear program to ensure its peaceful nature. Meanwhile, Iran wants the West to relieve sanctions imposed on the country.
Iran and the P5+1 group, including Britain, China, France, Russia, the United States plus Germany, held a two-day nuclear meeting in Vienna in March. Both sides agreed to hold the next round of talks on May 7.
Iran and the group struck a six-month interim deal in Geneva last November, according to which Iran would suspend part of its controversial nuclear activities as of Jan. 20, while the western countries would lift some sanctions imposed on Iran.
