TEHRAN, Sept. 11 (Xinhua) -- Iran's Foreign Ministry spokesman Ramin Mehmanparast said Tuesday that the talks with the International Atomic Energy Agency (IAEA) over Iran's nuclear issue should be followed up within the technical and legal framework.
IAEA states that there are some concerns over Iran's nuclear program and has announced that they have some questions about it, Mehmanparast made the remarks during his weekly press briefing.
Also, Iran has some rights which are "inalienable" within the Non-Proliferation Treaty (NPT) and should be respected in the negotiations with the IAEA, he added.
The cooperation with the IAEA would be a step forward in case the issues pertaining to both sides are taken into consideration, said the Iranian spokesman.
The remarks by Mehmanparast followed the states by the UN nuclear watchdog chief on Monday who urged Iran to open access of its military base Parchin to inspectors "without further delay."
Yukiya Amano, Director General of the IAEA also expressed " frustration", as no concrete results have been achieved "despite the intensified dialogue between the Agency and Iran since January 2012."
"We consider it essential for Iran to engage with us without further delay on the substance of our concerns," Amano said in his opening statement to the IAEA board of governors.
Though Iran stated in a letter in late August that the allegation of nuclear activities at Parchin was "baseless", "the activities observed further strengthen our assessment that it is necessary to have access to the location at Parchin without further delay in order to obtain the required clarifications," Amano added.
On Monday, Iran's permanent representative to the IAEA, Ali Asghar Soltanieh, responded to Amano's remarks saying that Tehran would agree on a new modality with the UN nuclear watchdog for further investigations if the latter observes the Islamic republic 's national security and submits solid documents on alleged studies, Press TV reported.
"As we have proved during the past years, we will continue to interact with the agency to prove the baseless nature of the claims but the framework for our work should be undoubtedly determined first," Soltanieh was quoted as saying.
He added that the framework should absolutely observe Iran's security considerations as a criterion.
The Iranian diplomat noted that there have been differences of opinion during talks between Iran and the IAEA and some of them have been already resolved.
"As long as the main considerations pertaining to Iran's national security and our basic demand on presenting alleged documents by the IAEA are not included in the text, the framework will not be agreed upon," said Soltanieh.
The West suspects that Iran's nuclear programs may have weapon dimensions, which was denied by the Islamic republic.
Representatives from Iran and the five permanent members of the UN Security Council plus Germany, known as P5+1, have held their first meeting in 14 months in April in Istanbul, followed by meetings in Baghdad and Moscow.
