Iran is prepared to reach a good agreement in nuclear deal negotiations due to start in Vienna at the end of the month, Foreign Minister said on Wednesday.

Iran PressIran News: Hossein Amir-Abdollahian said on Twitter that chief nuclear negotiator Ali Bagheri "engaged in successful talks in Europe."

Bagheri has so far traveled to France and Germany and will visit Britain on Thursday."At the negotiating table in Vienna, we are ready to deliver a good agreement. The return of all parties to their commitments is an important and leading principle," Amir-Abdollahian said on Twitter.

Talks to revive the US-abandoned 2015 nuclear deal, officially known as the Joint Comprehensive Plan of Action (JCPOA) are set to resume on November 29.

Iran has fulfilled all its obligations since the final agreement was reached in 2015, and the International Atomic Energy Agency (IAEA) has repeatedly confirmed Iran's adherence to its commitments in several reports.

The US administration now claims that it wants to return to the JCPOA, which has not only failed to take effective action to gain Iran's trust but has also continued to impose unilateral and illegal sanctions on Iran, even as no marked change is seen in the anti-Iranian policy of the US administration under the Democrats.

So far, six rounds of negotiations have been conducted in Vienna between the United States and other parties to revive the JCPOA. The sides say tangible progress has been made in the talks, but some differences remain.
