Iranian deputy foreign minister and senior member of Iran nuclear negotiating team Abbas Araqchi said on March 4 that the first day of technical talks in Vienna will cover Arak heavy water reactor and uranium enrichment issue will be discussed on March 6, Iran's IRNA news agency reported.
He went on to say that the agenda of the technical meeting by experts of Iran and P5+1 in Vienna will cover enrichment of uranium as well as removing ambiguities on Arak heavy water reactor.
The expert meeting in Vienna will take about three to four days and it might take longer if sounds necessary, he added.
Araqchi said that Iran never lets other issues except the country's nuclear programs to be raised in the technical meeting in Vienna.
Commenting on the upcoming visit to Tehran of EU foreign policy chief Catherine Ashton, the deputy minister said the visit is to take place as scheduled on Saturday night.
She is to confer with Iranian President Hassan Rouhani, Foreign Minister Mohammad Javad Zarif as well as several senior officials on issues of mutual interests, Araqchi remarked.
He noted that Iran hopes to reach a comprehensive agreement with the western governments to end decade-long nuclear dispute.
He made it clear that Iran is not optimistic about the good faith of the western governments.
Iran believes that the western governments are aware of civilian nature of the Iranian nuclear program and have used it as a pretext to strike a blow to Iran.
Iran and the P5+1(Russia, China, France, Germany, UK and the US) held meetings in Vienna in February to work on a comprehensive deal. The two sides signed an interim deal on Iran's nuclear energy programme in Geneva on November 24, 2013. The deal took effect on Jan. 20.
Under the agreement, six major powers agreed to give Iran access to its $4.2 billion in revenues blocked overseas, if the country fulfils the deal's terms which offer sanctions relief in exchange for steps on curbing the Iranian nuclear program.
Iran and P5+1 aim to continue their talks to reach a final agreement to fully resolve the decade-old dispute over the Islamic Republic's nuclear energy program.
The U.S. and its Western allies suspect Iran of developing a nuclear weapon - something that Iran denies. The Islamic Republic has on numerous occasions stated that it does not seek to develop nuclear weapons, using nuclear energy for medical research instead.
