Three days of intensive talks about Iran's nuclear program concluded early Sunday without an agreement, though key players insisted they believed the process is moving in the right direction.
"A lot of concrete progress has been achieved, but some differences remain," European Union foreign policy chief Catherine Ashton told reporters in Geneva, Switzerland.
Iranian Foreign Minister Javad Zarif echoed that sentiment, saying "hopefully we will be able to reach an agreement when we meet again."
"I think we are all on the same wavelength, and that's important," Zarif said. "And that gives us the impetus to go forward."
Chief International Correspondent Christiane Amanpour weighed in on "New Day" Monday and said Zarif said there was the possibility for an understanding or an agreement this weekend.
She adds, "Now, there are many who believe that was maybe an overly optimistic assessment, believe even as he was saying it. Hoping this would actually create momentum to having a deal." (SEE FULL INTERVIEW ABOVE)
That didn't prove to be the case this time, though the parties - including Zarif and Ashton - will meet again November 20.
Both Ashton and Zarif fielded questions posited on the assumption France blocked a resolution this time around. But neither singled out any one party, with the Iranian foreign minister saying differences among the countries are only "natural ... when we start dealing with the detail."
