MOSCOW. April 2 (Interfax) - The participants in the negotiations between the P5+1 group of countries and Iran in Lausanne have come to a common understanding as regards the future of the UN Security Council's sanctions against Iran, while the lifting of the unilateral sanctions from the country remains a substantial stumbling block, Russian Foreign Ministry spokesman Alexander Lukashevich said.
"A mechanism for lifting the unilateral sanctions from Iran still remains a serious matter of controversy," Lukashevich said at a news briefing in Moscow.
"As concerns the sanctions imposed by the UN Security Council, the participants in the negotiations and Russia have an understanding on the matter," he added.
Lukashevich also referred to Russian Foreign Minister Sergei Lavrov as saying that "it can be said quite confidently that agreements in principle have been achieved at the ministerial level on all key aspects of a final settlement of this problem, which experts now have to put on paper."
