The fifth round of nuclear negotiations between Iran and the world powers ended on Friday June 20 with plans to meet again on July 2.

Iranian Foreign Minister Mohammad Javad Zarif was quoted as saying that that there are still many differences regarding the content and form of the the comprehensive agreement that the parties are trying to draft.

According to IRNA, Zarif maintained that in view of the length of the dispute, it’s natural that there would be difficulty when moving toward the draft of a final agreement.

He said: “The other side is still asking for too much…. We have remained logical from the start and spoken according to international rights. We have come here to reach a resolution and have no need to waste time.”

This round of talks began on Monday June 16, and the parties are aiming to draft the final agreement by July 20, the deadline set out in the interim deal reached last November.
