Ashton & Zarif

Two days of intense nuclear talks between Iran and the world powers ended on an upbeat note with plans to resume talks on November 7 and 8.

EU foreign policy chief Catherine Ashton referred to the meeting as “their most detailed talks ever” on Iran’s nuclear program. Both sides described the talks as “substantive and forward-looking.”

The world powers are examining a proposal from Iran, and Iranian Foreign Minister Mohammad Javad Zarif said he expected them to take some time to “digest and respond to it.”

White House spokesman Jay Carney also expressed some optimism, saying Iran had shown “a level of seriousness and substance” that had not been seen before.

Iran’s Deputy Foreign Minister Abbas Araghchi has said that surprise visits could be part of the “last steps” toward an agreement, as well as a reduction in uranium-enrichment levels.
