Herman Van Rompuy, president of the European Council, called it an important step toward “providing assurances that guarantee the peaceful nature of the Iranian nuclear program.”
Russian President Vladimir Putin, whose government also participated in the talks, said the agreement vindicated Russia's calls for a diplomatic solution.
“The result of Geneva is a win for all, showing once again that by working collectively and with mutual respect it is possible to find answers to current international challenges and threats,” Putin said in a statement released by the Kremlin.
