VIENNA, Feb. 19 (Xinhua) - All sides in the ongoing Iranian nuclear talk are continuing working hard in a determinative way to make progress, a spokesman of the European Union's foreign policy chief Catherine Ashton said Wednesday.
Spokesman Michael Mann made the comments in the press center after he was back from the Palais coburg hotel, where the meeting is being held.
He said the negotiation atmosphere is always good and the talk is "substantive," without giving details.
The three-day Iranian nuclear P5+1 talk between China, Britain, France, Russia, the United States plus Germany, and Iran entered its second day session Wednesday in Vienna.
The talk is going into details of the agendas proposed by all sides in the first-day talk, diplomats told Xinhua.
But they noted this is the first step to make a comprehensive deal which would be in a long process, and many issues have yet to be discussed.
Once the agenda is agreed, it would serve as a framework or guide for the comprehensive deal for the Iranian nuclear issue, according to diplomats.
Mann confirmed that Ashton would leave for Brussels to attend an extraordinary meeting of EU Foreign Ministers on Ukraine scheduled for Thursday.
The Iranian nuclear talk is based on the interim deal agreed in Geneva November 2013, in which Iran agreed to suspend some controversial nuclear activities while western states agree to ease sanctions against Iran in return.
The parties involved are striving to clinch a comprehensive deal over the decade-long nuclear standoff.
