TEHRAN (FNA)- Iranian Supreme Leader's top aide Ali Akbar Velayati underlined that the western countries will fail to prevent Iran from making progress through raising excessive demands.

"The West cannot impose its demands which are aimed at preventing the country's progress in scientific and technological fields," Velayati told reporters on Tuesday.


He pointed to Supreme Leader Ayatollah Seyed Ali Khamenei's recent statements on Tehran-Group 5+1 (the US, Russia, China, France and Britain plus Germany) nuclear talks, and said, "As the Supreme Leader said in his recent meeting, the West will not succeed if it intends to prevent Iran's peaceful progress."


Velayati underlined that the negotiations with the West will continue only within the framework set by the Supreme Leader.


"As Iran's Supreme Leader has said it is not Tehran, but the US whose hands are tied up in the negotiations," he added.


Addressing a meeting with the commanders and personnel of the Iranian Air Force and Air Defense in Tehran on Sunday, the Supreme Leader complained that the behavior of the Americans and their European allies in the negotiations is illogical as they expect all their excessive demands to be met, "but this is not the way of negotiation".


Ayatollah Khamenei approved of the Iranian officials' standing up to the other side's excessive demands, and said, "The Islamic ruling system acts on a logical basis in the nuclear talks, but the other side has no logic and is pursuing irrationality by relying on bullying."


The Supreme Leader reiterated that the Iranian nation will not tolerate bullying, excessive demands and illogical behavior.


The 10th round of negotiations between Iran and the six world powers was held in Vienna from November 18 to 24, where the seven nations decided to extend the talks until July after they failed to strike an agreement.


The latest round of the nuclear talks between the two sides was held at the level of deputy foreign ministers in Geneva, Switzerland, on January 18.


The two sides decided to continue their talks in February.


Both Iran and the G5+1 negotiators have underlined that cutting a final deal before the July 10 deadline is possible.
