The EU foreign policy chief says Iran and the P5+1 group of countries are close to reaching a "good deal" over Tehran's nuclear program, IRNA reported.
'I believe a good deal is at hand,' said Federica Mogherini in the Latvian capital city of Riga on Friday, adding, 'I also believe that there is not going to be any deal if it is not going to be a good deal.'
The EU official also stated that the two sides' political will, and not the technical issues, now defines the fate of negotiations, Press TV reported.
Earlier in the day, Mogherini gave a positive assessment of the technical talks between the deputy foreign ministers of Iran and the six world powers in the Swiss city of Montreux on Thursday.
'The meetings were constructive and useful. Some progress was made and a better understanding on some of the issues emerged,' her office said in a statement.
'The (parties) will continue to work on the remaining gaps and will meet again very soon,' the statement added.
On Wednesday, Iran's negotiators also held quadrilateral deputy-level talks with Hans Dieter Lucas from Germany, Simon Gass from Britain and Nicolas de Riviere from France.
On the same day, Iran's Foreign Minister Mohammad Javad Zarif and his American counterpart, John Kerry, wrapped up intense negotiations in Montreux. Head of the Atomic Energy Organization of Iran (AEOI) Ali Akbar Salehi and US Energy Secretary Ernest Moniz also attended the talks.
Iran and the P5+1 countries - Russia, China, Britain, France, and the United States plus Germany - are seeking to seal a comprehensive nuclear deal by July 1. The two sides have already missed two self-imposed deadlines for inking a final agreement since they signed an interim one in the Swiss city of Geneva in November 2013.
