TEHRAN (FNA)- Iranian Supreme Leader's top adviser for international affairs Ali Akbar Velayati underlined that the West should be blamed for its excessive demands in the negotiations in case the ongoing talks between Tehran and the six world powers fails to produce any result.

"The Islamic Republic of Iran believes that the peaceful use of the nuclear energy is the (inalienable) right of the Iranian nation, and it welcomes the negotiations accordingly; but some western countries are trying to push the negotiations into a deadlock on different pretexts; the Islamic Republic of Iran will stand up to (their) excessive demands," Velayati said, addressing a meeting with a group of Chinese officials and experts in Beijing on Tuesday.

The top Iranian advisor reiterated that the West has always created problems for Iran over the past 35 years, including support for terrorist groups, and said, "Some Western countries, including the US, have played a role in the creation of the ISIL with the help of some regional countries as mentioned by (former US Secretary of State) Hillary Clinton in her book... ."

Velayati reiterated that the ISIL has been created, equipped and trained by the western countries and they commit their crimes against the oppressed nations of the region, and said, "� of course we should explicitly announce that the axis of resistance comprising Iran, Syria, Lebanon, Yemen and Iraq have resisted against this crimes and threats and they will continue to do so."

On Monday, Iranian Deputy Foreign Minister Majid Takht Ravanchi reiterated Tehran's request from the Group 5+1 (the US, Russia, China, Britain and France plus Germany) to drop their excessive demands during the nuclear talks to reach a final deal.

"We hope that the other side tries to reach a comprehensive agreement before the specified time by stopping its insistence on its maximalist positions; although we are not under a time-limit pressure and are after an agreement that envisages all our rights," Takht Ravanchi said in a meeting with his Austrian counterpart Michael Linhart in Tehran.

After nine days of hard work in Lausanne, Switzerland, Iran and the G5+1 reached an understanding on April 2 which laid the ground for them to start drafting the final nuclear deal over Tehran's nuclear energy program ahead of a July 1 deadline.

Reading out a joint statement at a press conference with EU foreign policy chief Federica Mogherini in Lausanne on April 2, Iranian Foreign Minister Mohammad Javad Zarif said according to the agreement, all the US, EU and UN Security Council sanctions against Iran would be lifted under the final deal.

The seven nations are now drafting the final deal.

But earlier this month, Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi complained that the world powers welsh on what they agree to undertake in the nuclear talks with Iran.

"We welcome interaction as Iran's logic is based interaction with the world. We are not after confrontation," Salehi said in Tehran, addressing a ceremony to commemorate the Iranian nuclear scientists assassinated by the foreign spy agencies.

He said the nuclear negotiations with the G5+1 are progressing well, but "they are lowballing with regard to certain issues that we had agreed on."

Salehi underscored that Tehran is after a nuclear agreement with the world powers "but not at any price".

His remarks came after the US Senate advanced a legislation that would allow the Congress to review a nuclear deal between world powers and Iran. The bill turned into a law by President Obama's endorsement.
