VIENNA—U.S. Secretary of State John Kerry arrived in Vienna Friday to launch a top-level push to meet next week’s deadline for talks on Iran’s nuclear program, which aim to curb Teheran’s nuclear activities in exchange for sanction relief.
But a senior Iranian official warned that negotiations are hampered by differences not only between Tehran and the six other countries it is bargaining with but internally among the six as well.
Kerry was the first to arrive Friday evening, with diplomats from Iran, Britain, Germany, Russia, France and China expected in the Austrian capital over the coming days.
Negotiations could spill over into early July, despite the extra diplomatic muscle packed by the senior diplomats. Ahead of Kerry’s arrival, Iranian Deputy Foreign Minister Abbas Araghchi, Iran’s top negotiator, told Iran’s IRNA news agency that — while “on the whole we are making headway” — progress was slow and hard.
