Iranian Foreign Minister Hossein Amir-Abdollahian did not rule out direct talks with the United States if the prospect of a good agreement appeared, Mehr reported.

"If we reach a stage in the negotiation process where a good agreement is needed to have a dialogue with the United States, we will not ignore it," Hossein Amir-Abdollahian said.

"The United States sends messages calling for direct talks with us. Our talks with the United States are taking place through Mora and one or two JCPOA members in Vienna," the top diplomat added.

"Our criticism of the three European countries is that they have not taken any forward-looking and constructive initiatives, but they have tried to play a constructive role in the negotiations in recent weeks. Even today, France does not play the role of a bad cop. China and Russia are trying to play a constructive role in the negotiations and these two countries are active in conveying the issues," he added.
