Two European diplomats with knowledge of the talks that took place in Doha this week have said that even though there was no substantial progress in the talks, efforts to revive the landmark 2015 deal between Iran and the P4+1 may continue after US President Joe Biden's visit to West Asia.

A third person familiar with the talks, according to Bloomberg, said that efforts to revive the deal may resume in the Qatari capital after the visit.

According to one of the European diplomats, Iran's negotiating team at the talks repeated its grievances over the US-E3-sponsored IAEA resolution directed against Iran which claimed Iran was not cooperating with agency monitors.

At the time, Iran issued a detailed response in response to the agency's resolution, refuting its claims.

As for the talks, the search for a compromise between parties may take until the third quarter, after which the US will be holding Congressional elections.

Iran's Foreign Minister, Hossein Amir-Abdollahian, said in a statement on Thursday that Tehran is keen on pursuing the talks until a good, lasting agreement is reached.

Meanwhile, Gulf nations, according to Bloomberg, are being encouraged to play a more active role, since the EU's role as mediator is reaching its limit.

“The US also must outline a strategy for Middle Eastern stability that is not merely based on containment and confrontation with Iran or securing a short-term reduction in oil prices,” Iran researchers Vali Nasr and Maria Fantappie wrote Friday in the US journal of Foreign Affairs.  
 
“It must establish a durable framework for preventing conflict,” they wrote. “The most effective way to do this would be to conclude a new nuclear deal with Iran.”
