"I think that raising this issue is a psychological war waged by the Americans," Chairman of the parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi told FNA on Saturday.
His remarks came after a senior Obama administration official was quoted by Los Angeles Times daily on Thursday as saying that the world powers could break off nuclear negotiations in Vienna this month unless Iran begins to make concessions.
The official said that though the six world powers and Iran have an option to continue the talks on Iran's disputed nuclear program for six months beyond the current July 20 deadline, that won't happen unless both sides believe it is worthwhile.
Boroujerdi downplayed the remarks, and warned, "The Americans know that if they rock the boat, Iran will resume its pervious measures at a very high speed and will continue them."
He underlined that uranium enrichment at industrial scale for peaceful uses is one of Iran's national projects and a redline that Tehran will never cross.
The sixth round of talks between Tehran and the Group 5+1 (the US, Russia, China, Britain and France plus Germany) headed by Iranian Foreign Minister Mohammad Javad Zarif and EU foreign policy chief Catherine Ashton officially started in Vienna this week.
On Wednesday, Zarif held a bilateral meeting with Ashton which was focused on drawing up agenda of the Vienna 6 talks.
On Friday, Iranian and EU officials in a meeting in Vienna held another round of talks on drafting a final agreement between Tehran and the G5+1 over the former's nuclear program.
During the meeting in the Austrian capital, senior Iranian nuclear negotiator Seyed Abbas Araqchi and EU Deputy Foreign Policy Chief Helga Schmidt started bilateral consultations on the final deal.
Araqchi voiced satisfaction in the progressive trend of the sixth round of nuclear talks between Iran and the six major world powers in Vienna, but cautioned the six world powers and international bodies not to try to include new issues in the negotiations.
The UN High Commissionaire for Human Rights Navi Pillay had on Thursday in a press conference on the sidelines of the Vienna nuclear negotiations between Iran and the G5+1 requested the western negotiating delegations to include human rights issue in Iran in their nuclear negotiations with Tehran in full details.
"All the sides of these negotiations, too, are fully aware of the fact that the human rights issue is totally unrelated to the matter of discussions in our ongoing nuclear talks," Araqchi pointed out.
He also rejected some media reports about a reduction in the number of centrifuges that Iran has demanded to have during the talks with the G5+1.
A Thursday report by Reuters cited “a Western diplomat” as saying that “Iran has reduced the number of centrifuges it wants". According to the report, diplomats claimed that the Islamic Republic had signaled it would settle for a lower figure than 50,000 centrifuges.
"All the figures which are reported on the number of centrifuges are the figment of the imagination of some foreign media," Araqchi said.
Also on Thursday, the Iranian foreign minister wrote on his Facebook page that Western media speculations on the nuclear discussions between Tehran and the G5+1 should not be taken seriously as they attempt to influence the negotiations instead of reporting the events.
Also in a video message on the eve of a new round of talks with the six world powers on Wednesday, Zarif asked his counterparts from the sextet not to miss the present opportunity for striking a deal with Iran and putting an end to an unnecessary crisis.
Iran and the Group 5+1 sealed an interim deal in the Swiss city of Geneva on November 24, 2013 to pave the way for a full resolution of their decade-old dispute over the former’s nuclear standoff with the West. The deal came into force on January 20.
Under the Geneva deal, dubbed the Joint Plan of Action, the six countries undertook to provide Iran with some sanctions relief in exchange for Tehran agreeing to limit certain aspects of its nuclear activities during a six-month period.
Zarif told reporters after the latest round of talks with the six world powers held in Vienna on June 16-20 that although the seven nations have started compiling the draft deal, the harsh stance taken by the western powers, which is reflected in their excessive and maximum demands shows that they are not fully ready to enter serious negotiations to attain a final solution to the decade-old standoff.
He stressed that Iran would not give up its rights, and would continue resistance until restoring all its nuclear rights.
