Diplomats and experts from six world powers and Iran have staffed up to pursue intensified, almost “constant” contacts to try to reach a final nuclear deal, a senior US administration official said Friday, ahead of a second round of political directors-Iran nuclear talks in Vienna next week. The parties have already agreed that sanctions relief in a final deal would be phased in, step by step, in response to specific action that Iran takes, the official said.
“These comprehensive negotiations will not be done for three days a month by the political directors,” the senior US administration official said. “Our experts have been and will be in constant contact between these rounds.”
