Iran on Wednesday reiterated that it would reject a reported EU proposal if it fails to acknowledge its right to get peaceful nuclear energy, the official IRNA news agency reported.
"If our right will not be officially recognized, other proposals would automatically be canceled out," Gholamreza Aqazadeh, Head of the Atomic Energy Organization of Iran, was quoted as saying.
"The nuclear technology in Iran has become an indigenous and self-motivated phenomenon," Aqazadeh said, stressing that the use of nuclear technology is among the absolute rights of all countries.
He noted that "Iran submitted the Europeans its proposals and programs on the country's nuclear activities. Now it is waiting for their reaction towards these proposals and programs."
The three European countries of France, Germany and Britain are reportedly going to make a proposal to encourage Iran to halt its fuel cycle work related to uranium enrichment.
According the proposal, Iran would get access to imported nuclear fuel and other offers in return for a downright suspension of its fuel cycle work.
However, Aqazadeh said that Iran has yet not received any proposal from the European side.
"No specific and official offer has been received from the Europeans yet," he said, underlining that "what is important to us is those principles which are not changeable."
"We are waiting to receive their proposals. We will continue negotiations if those offers are consistent with our principles," Aqazadeh said.
Other top Iranian officials have also set the same precondition for any proposals negotiable to Iran.
Hassan Rowhani, Secretary of Supreme National Security Council and chief nuclear negotiator, said on Monday that Iran has its principles on which Tehran cannot give in, referring to the country be allowed to develop civil nuclear technology.
Foreign Ministry spokesman Hamid-Reza Asefi said on Sunday that the only proposal acceptable to Iran was one that would be in its national interest.
Iran and Europe will hold nuclear talks on Thursday, during which the three European countries would submit the proposal, it was reported.
The International Atomic Energy Agency last month adopted a resolution, which urges Iran to suspend all of the activities related to uranium enrichment and fully cooperate with the inspectors to clear up all related issues.
The resolution has been criticized and rejected by Iran, which termed it as "illegal".
Tehran has been denying the US accusation of developing nuclear weapons, asserting that it is politically motivated and Iran's nuclear research is fully peaceful.
