Iran's foreign minister, Mohammad Javad Zarif, has insisted Iran has the "political will" to reach a deal as the next round of talks between Iran and six world powers to agree a first-step nuclear deal begins in Vienna.
"We believe we can reach an agreement and we have come here with the political will to reach a final agreement," Zarif said on Monday after meeting the EU foreign policy chief, Catherine Ashton, in Vienna.
"If all sides enter the talks with the political will to resolve the issue, we will be able to reach positive results but it will take time," he said in statements carried by the IRNA state news agency.
The first high-level talks since an interim deal was agreed on 24 November the result of months of bargaining have been preceeded with expressions of pessimism from US and Iranian camps.
