“The fourth round of negotiations in Vienna has ended.

The JCPOA participants in their meeting today noted that “good” or “significant” progress has been made and that the agreement is “within reach,” Ulyanov wrote on his Twitter.

He said that "the joint commission will resume its work early next week."

“I hope the fifth round will be the final one,” added the permanent representative.

Earlier, Ulyanov said that the Iranian side, during a meeting with the Russian delegation in Vienna, confirmed its intention to achieve a quality result on the issue of the full restoration of the nuclear agreement.
