Iran's negotiations with IAEA and the P5+1 group move into positive direction, Iranian Foreign Ministry spokesman Ramin Mehmanparast said today at the press conference, Press TV reported live.
"The talks move into positive direction and the results have improved compared to the past meetings," Mehmanparast said. "Reciprocal measures should be taken to achieve desired results."
The spokesman underscored that Iran's nuclear rights for peaceful purposes must be recognized.
With regard to the nuclear talks between Iran and the P5+1 group in Kazakhstan, Mehmanparast said that the most important thing is that general understanding was reached, and optimistic atmosphere was created.
"During the negotiations there were some responses made to the proposals Iran made previously," Mehmanparast noted. "Other measures may be necessary to reach the final agreement."
He further said that the new approach by the P5+1 group made "the proposals worthy to be addressed and explored".
"This however is only the first step, as there will be more meetings after the negotiations in Kazakhstan," he added.
Mehmanparast also touched upon some countries and media outlets and how they presented the Iran-P5+1 group talks' outcome.
"It is surprising that some Western and regional countries, along with their media outlets adopt different approach, trying to actually tarnish the atmosphere and posotive results of the negotiations," Mehmanparast said.
On Monday, the head of the UN atomic agency called on Iran to allow immediate access to the Parchin military base where it suspects nuclear weapons research took place.
Yukiya Amano said that this should be granted "without further delay" and without waiting for stalled talks to conclude an agreement on investigating other alleged "weaponisation" activities.
"I request Iran once again to provide access to the Parchin site without further delay, whether or not agreement has been reached on the structured approach," Amano told the International Atomic Energy Agency board of governors meeting.
"Providing access to the Parchin site would be a positive step which would help to demonstrate Iran's willingness to engage with the Agency on the substance of our concerns," he said, according to the text of his remarks at the closed-door gathering.
Iran and P5+1 group have wrapped up the nuclear negotiations in Kazakhstan on Feb. 27 after two days of talks.
The sides agreed to hold expert level talks in Istanbul on 17-18 March, which will be followed by another Iran-P5+1 talks in Kazakhstan.
In 2012, representatives of P5+1 group and Iran held three rounds of talks in Istanbul (April 14), Baghdad (May 23-24) and Moscow (June18-19). None of these meetings resulted in breakthroughs on disputed nuclear issues.
Previously talks between the "Six Powers" and Iran were not conducted for over a year.
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 researches instead.
Despite the rules enshrined in the Non-Proliferation Treaty (NPT) entitling every member state, including Iran, to the right of uranium enrichment, Tehran is now under four rounds of UN Security Council sanctions for turning down West's calls to give up its right of uranium enrichment.
