He made the remarks at a joint press conference with his German counterpart, Guido Westerwelle, in Berlin on Tuesday, Reuters reported.
Kerry said that he hopes Iran will address what he called the international community’s concern over its nuclear energy program.
He added that he wanted to express "hope that these talks can advance” and "that Iran itself will make its choice to move down the path of a diplomatic solution. There is a diplomatic path, there is a clear way through this and I want these talks to have a chance to work through before I comment further.”
Iran and the P5+1 group -- Britain, China, France, Russia, the United States, and Germany -- have wrapped up their first round of talks in Kazakhstan’s biggest city, Almaty, with each side offering its own package of proposals.
The P5+1 reportedly demanded that Iran stop enriching uranium up to 20 percent, ship out its stockpile of enriched uranium and shut down the Fordow uranium enrichment facility in the province of Qom, and in return, the Western governments would ease gold, petrochemical and banking sanctions against Iran.
Secretary of Iran’s Supreme National Security Council Saeed Jalili is heading the Islamic Republic’s negotiating delegation. The P5+1 representatives are led by European Union foreign policy chief Catherine Ashton.
Iran and the P5+1 group have held several rounds of talks with a focus on Iran’s nuclear energy program. The last round of negotiations between Iran and the P5+1 group was held in Moscow in June 2012.
Kerry flew to Berlin late Monday to meet with senior German officials and is set to travel to Paris to hold talks with French President Francois Hollande before heading for Rome. The last leg of his tour will take him to Turkey, Egypt, Saudi Arabia, the United Arab Emirates, and Qatar.
