TEHRAN, June 20 (Xinhua) -- Iran will decide on the number of its centrifuges for uranium enrichment, Iran's Foreign Minister Mohammad-Javad Zarif said at the end of the five-day nuclear talks in Vienna on Friday.
"Centrifuges belong to us and we will decide on them.... The enrichment program also belongs to Iranian people and we will not negotiate over those things," Zarif was quoted as saying by official IRNA news agency.
The foreign minister's remark was a reaction to the West demands in the talks which urged Iran to dramatically lower its uranium enrichment capacity and wanted Tehran to maintain only a few hundred centrifuges.
"We will not cooperate on unlimited questions" and on demands about Iran's nuclear program, he said, adding that "parts of these questions are allegations and propaganda against us and (these claims) cannot be endless."
Of the negotiating countries over Iran's nuclear program, the United States has exerted most of the pressures, including the economic sanctions, on Iran.
The West "must make the most difficult decisions to lift the sanctions" in the course of a comprehensive nuclear deal, Zarif said, adding that "we hope they will be ready for making such decisions."
According to the interim Geneva nuclear agreement last November, Iran had to take steps to alleviate the concerns of the world powers over its nuclear program in exchange for a partial lift of economic sanctions posed by the West.
Iran and the P5+1, including five permanent members of the U.N. Security Council plus Germany, held fresh round of nuclear negotiations in Vienna, the fifth of its kind, over the past five days, but they did not make considerable progress in their " intensive and difficult" talks.
Next round of talks were slated for July 2 for further work on the draft of a final nuclear accord.
