Key talks between Iran, the United States and other nations over Iran’s disputed nuclear program are resuming today in Geneva. Iran is expected to introduce a proposal to curb its uranium enrichment efforts in a bid to ease crippling economic sanctions. The meetings include the so-called P5+1 group, which consists of the United States, Britain, China, Russia, France and Germany. Catherine Ashton, the European Union’s foreign policy chief, who is leading the negotiations, says she is cautiously optimistic.

Catherine Ashton: “I hope that what we’ll have here is a very productive two days, an opportunity to explore both the proposals that we have put on the table, but also ideas that are coming from Iran. I hope that in the course of that time there will be an opportunity to really go into the detail and to explore the possibilities.”
