Iran's Foreign Minister said on Wednesday that his country's assessment of the Doha talks was positive.

During a phone conversation with his Qatari counterpart Mohammed bin Abdulrahman Al Thani, Amir-Abdollahian said: "We are serious in reaching a good, lasting deal if the US acts realistically."

The Iranian diplomat said Iran's chief negotiator is attempting to come up with creative solutions to reach a lasting agreement, noting that Iran is willing to move forward with the talks until a reasonable deal is reached.

For his part, Qatar's Foreign Minister said he also believed that the Doha talks were constructive, adding that Doha will spare no efforts in ensuring that all parties abide by their commitments and that the results sought out by Tehran are reached.

The advisor to the Iranian negotiating team, Seyed Mohammad Marandi, said yesterday that "there was never any expectation that these negotiations would culminate in an agreement over a couple of days."

In an interview for Al Mayadeen, Marandi added that Tehran does not take US officials' media statements seriously, noting that the Americans should provide the guarantees that Iran demands to confirm that "history is not repeated."

He added that "Iran doesn't expect anything more, but it won't expect anything less", stressing that "there has been movement on the American side."

The EU's Deputy Secretary-General Enrique Mora said Wednesday that indirect talks in Doha between Iran and the United States over reviving the 2015 Joint Comprehensive Plan of Action (JCPOA) with major powers have ended without reaching the intended progress.

"Unfortunately, not yet the progress the EU team as coordinator had hoped for. We will keep working with even greater urgency to bring back on track a key deal for non-proliferation and regional stability," Mora tweeted.
