Russia's�Foreign Minister Sergey Lavrov says no insurmountable problems are left�at nuclear negotiations between Iran and the P5+1 countries.

Lavrov said Thursday that�the two sides agreed in Vienna, Austria�that the quality of a final nuclear deal with due account of Iran's interests is most important.

Russia's top diplomat referred to anti-Iran sanctions, saying Moscow wants Iran's arms embargo "lifted as soon as possible."

"We are in favor of lifting the embargo as soon as possible and will support a decision made by Iran's negotiators," Lavrov pointed out.

Meanwhile, Russian Deputy Foreign Minister Sergey Ryabkov has compared the final round of the ongoing talks between representatives from Iran and the five permanent members of the UN Security Council � Britain, China, France, Russia and the United States, plus Germany � over Tehran�s nuclear energy program to the last and hardest stage of ascending Mount Everest.

"We are working together with colleagues from P5+1 group on proposals made by Iran on Tuesday. This work is hard and time-consuming. We did not meet the July 7 deadline. Those are right who say that talks are like ascending Mount Everest," Ryabkov said on Thursday.
