MOSCOW, April 23. /TASS/. Russia will call for lifting arms embargo against Iran at the upcoming talks in Vienna on Friday at the level of political directors of Tehran and six world powers, Russian Deputy Foreign Minister Sergey Ryabkov has told reporters.

One of the priorities and important tasks is to ensure that all the participants of the negotiations "recognize the foremost need to cancel the existing weapons embargo against Iran," Ryabkov said

"If any partners at talks pose a question on the possibility of returning to sanctions against Iran in a hypothetic situation of its failure to fulfill its commitments, then there should be no automatism in this process," the diplomat said.

The decision on this should be taken in accordance with the procedures of the UN Security Council, in other words through the voting in the Security Council and by adopting a respective resolution, he added.

Iran and P5+1 group (Russia, US, UK, China, France and Germany) reached a breakthrough agreement in Switzerland’s Lausanne on April 2 on containing Tehran’s nuclear program in exchange for gradual sanctions relief. The deadline for coordinating the final agreement is June 30.
