TEHRAN - Iran and the world powers will hold an expert-level meeting in Vienna on weekend to discuss Geneva nuclear deal, Iranian Foreign Ministry spokeswoman Marzieh Afkham announced here on Tuesday.

The two-day meeting on Dec. 8-9 is aimed to prepare the implementation of the deal reached on Nov. 24 in Geneva between the Islamic republic and the P5+1 group, including the United States, Britain, France, Russia and China plus Germany, she said.

Experts from the UN nuclear watchdog (IAEA) will also participate in the meeting as observers, so that they could obtain an accurate understanding about the deal, said Afkham at her weekly press briefing.

Implementation of the deal could take time because world powers need time for preparation, she said.

Afkham also stressed the Fact Sheet released by the White House was only the one-sided American narration of the agreement. "The four-page Joint Plan of Action is clear on the obligations of all sides."

The White House interpretation of the deal contained much stronger wording than the more balanced Joint Plan of Action stemmed from a marathon negotiation in Geneva. The Fact Sheet called the deal "a set of initial understandings that halts the progress of Iran's nuclear program and rolls it back in key respects. These are the first meaningful limits that Iran has accepted on its nuclear program in close to a decade."

Also, the Fact Sheet said Iran was committed to halt progress on the growth of its 3.5 percent enriched uranium stockpile which Iranian officials denied.

The United States and its allies will afford Iran with limited relief of sanctions on its oil, gold, petrochemicals, auto industries and civil aviation with an estimated value of about 7 billion U.S. dollars under the terms of the six-month nuclear deal.

In exchange, Iran agreed to halt enrichment above 5 percent and neutralizing its stockpile of near 20 percent uranium by means of dilution or converting. The document says Iran also agreed not to make advances of its activities at Natanz and Fordow enrichment plants and at the Arak reactor. (Xinhua)
