Bagheri Kani made the remarks in an interview with the Islamic Republic of Iran Broadcasting (IRIB) News Agency to elaborate on the talks resumed in the Austrian capital as of November 29.

Axar.az reports as the top nuclear negotiator announced, he is optimistic about reaching an agreement; however, the country will surely not be simple-minded as "our people" have bad experiences from the other side.

The atmosphere within the talks is based on mutual respect and very serious, Bagheri Kani added.

He went on to say that each side should defend its stance and give its reasons.

As he stressed, no approach has been seen as interruption to the talks.

The deputy foreign minister said that a full and comprehensive agreement has not been reached on many parts.

For instance, the two have reached agreement on the part of nuclear activities; meanwhile, some related issues had remained from the sixth round of talks about which the two have to continue negotiations, he noted.
