Iran says nuclear deal has to entail agreement on all subjects

Unless the negotiating parties in ongoing talks agree on all the subjects of discussions, there would be no nuclear agreement, Iranian Foreign Ministry spokeswoman Marzieh Afkham said Wednesday in weekly press briefing.

Asked whether there is a chance for an agreement in the following days, she said "the talks have legal and complex dimensions and we have to wait for the developments in the following days."

The ongoing talks between Iran and world's major powers in Switzerland are focused on narrowing down the existing differences on a number of topics pertaining to Iran's nuclear issue, Afkham said.

"The talks are very complicated and are at the crucial stage. The (Iranian) negotiating team is in for the intensive work days and they are trying to reduce the differences" over the country' nuclear issue, Afkham told the reporters.

"We have had good progress in the technical aspects (in the recent days) and most of the relevant problems have been solved," she said, adding that in the political and sanctions sectors the talks are continued.

The representatives from the P5+1 group, namely Britain, China, France, Germany, Russia and the United States, are scheduled to meet together and hold talks with Iran on Wednesday in Lausanne of Switzerland following the two-day bilateral talks between the Iran and the United States.

It has been over 15 months since Iran and the world's major countries agreed to come back to the negotiating table to discuss the controversial Iranian nuclear program.

Under an interim deal between Iran and the P5+1 inked in November, 2013, Iran said it would suspend critical nuclear activities in return for some ease of sanctions, with all sides seeking a final and comprehensive deal.

The six world powers had set a June 30 deadline to forge a final and comprehensive agreement, but the United States has said earlier that it hope to reach a "framework agreement" by the end of March. Enditem
