TEHRAN (FNA)- Tehran will not implement its undertakings before being assured of the world powers' firm decision for complying with any possible nuclear deal, Iranian Parliament Speaker Ali Larijani said on Sunday.

"Our negotiators should manage the scene of the talks with more attention and consider alternative scenarios for different conditions and the Islamic Republic will take no action before seeing the firm decision of the other side," Larijani said, addressing the legislators in an open session of the parliament in Tehran today.


He said conditions and analyses warn that the US is trying new deceptive methods to disrupt the nuclear talks, but Iran will continue the negotiations, but "they should naturally give clearer guarantees that continuing negotiations will yield results".


Yet, he said the US negotiators are unlikely to be so naive to imagine that they can boost their bargaining power through such tricky moves, rather, now "they need to tolerate a different and more cumbersome condition to (be able to) guarantee the agreement".


Larijani's remarks came after US President Barack Obama said that if Iran violated its undertakings even for an inch, all lifted sanctions would snap back again.


After Obama's statement, Iranian Supreme Leader's top adviser Ali Akbar Velayati cautioned the US officials to stop making statements that could damage the ongoing trend of the Iran-world powers talks, and said Tehran is not fond of appeasing the Americans, but is only seeking to establish its nuclear rights.


"We are not keen to reach an agreement with the Americans, but what is evident is that Iran wants to preserve its nuclear rights to be able to use nuclear energy within the peaceful framework of international regulations and it has taken part in the negotiations with the Group 5+1 (the US, Russia, China, France and Britain plus Germany)," the Iranian Supreme Leader's top aide told reporters on Saturday.


He noted that negotiations proved to the world and the international community that Iran had always been after the peaceful use of the nuclear technology and the people would remember that the enemies and ill-wishers had falsely accused Iran.


Velayati reiterated that Iran was only seeking to establish its nuclear rights, and stressed that any nuclear agreement between Iran and the six world powers should be "fair and balanced".


Obama's remarks came as a senior Iranian negotiator announced that representatives of Tehran and the G5+1 would kick start drafting a final nuclear agreement on Tuesday.


"Next Tuesday, the new trend and working on the draft (agreement) will kick start to get it ready for July 1, and we should prepare the generalities and details of that," Director General for Political Affairs at the Iranian Foreign Ministry and nuclear negotiator Hamid Baeidinejad said in Tehran on Tuesday night in a meeting with a number of Iranian university professors and lawyers.


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.


"Our decision today that will be the agreed base for the final text of the Joint Plan of Action (the final deal) is of vital importance," Zarif said, reading the joint statement at the press conference.


"Now we can start drafting the final agreement and its annexations by relying on the solutions achieved in the last few days," he said after eight days of marathon talks with negotiators from the six world powers.


"As Iran continues its peaceful nuclear program, the degree and capacity of its enrichment and the size of its (enriched uranium) stockpile will be limited for specific periods and Natanz will be the only enrichment center in Iran. Nuclear enrichment R&D on centrifuge machines in Iran will be conducted on the basis of an agreed timeline and level."


Zarif said Fordo would turn from a nuclear enrichment plant to a nuclear, physics and technological center, where Iran will receive international cooperation.


The Iranian foreign minister also said the country's Arak Heavy Water Reactor would remain in place after being redesigned and renovated through international cooperation, stressing that the facility would remain a Heavy Water Reactor in nature, but would produce plutonium which wouldn�t have the capability to be used for nuclear weapons production.


He said "there won't be any reprocessing at the Arak facility and its consumed nuclear fuel will be sent" abroad.


"A collection of arrangements have been agreed for supervising the implementation of the contents of the Joint Plan of Action (final deal) which will include Safeguard Code 3.1 and voluntary implementation of the Additional Protocol (to the NPT); the International Atomic Energy Agency (IAEA) will also use modern inspection technologies and will be given more agreed access to verify past and present issues," Zarif said.


He said Iran would partner in international nuclear projects, "including power plant and research reactor construction as well as nuclear safety and security".


Zarif stressed that all sanctions against Iran will be lifted.


He said all UN Security Council sanctions resolution against Iran would be annulled as they did not help the settlement of the nuclear standoff between Iran and the six world powers.


"The EU will terminate imposition of its nuclear-related economic and financial sanctions and the United States will also stop implementation of its nuclear-related financial and economic sanctions simultaneous with the implementation of Iran's major nuclear undertakings in a way that they are verified by the IAEA," Zarif said.


Zarif said the final deal would be endorsed by a UN Security Council resolution in a move to annul all the previous nuclear-related resolutions against Iran.


He said drafting of the deal would start soon to prepare the Joint Plan of Action by the July 1 deadline.
