Negotiations to revive the 2015 Iran nuclear deal will resume in the Austrian capital Vienna on Saturday, Iranian Deputy Foreign Minister Abbas Araqchi has announced following a recent break in the ongoing talks.

“The participants are expected to continue consultations on the possible return of the US to the nuclear accord and ensuring the full and effective implementation of this agreement,” Araqchi, who is Tehran’s top negotiator at the talks, wrote on Telegram.

US Deputy Secretary of State Wendy Sherman also said this week that talks on reviving the so-called Joint Comprehensive Plan of Action (JCPOA) “will start again over this coming weekend.” She said “there’s been a lot of progress” so far during the four rounds of negotiations, but refrained from speculating on when the final details will be nailed down.

The head of the Russian delegation in Vienna, Mikhail Uliyanov, earlier expressed optimism that the upcoming fifth round could well be the final one in securing the renewal of the deal. (RT)
