Iranian delegation to visit Vienna tomorrow

Iran said on Monday removal of U.S. sanctions is Tehran's red line in talks with world powers in Vienna to revive a 2015 nuclear deal, adding that talks will resume on Tuesday

An Iranian delegation on nuclear talks will visit Vienna tomorrow, an Iranian foreign ministry spokesman Saeed Khatibzadeh told a news conference Qazet.az reports.

Iran said on Monday removal of U.S. sanctions is Tehran's red line in talks with world powers in Vienna to revive a 2015 nuclear deal, adding that talks will resume on Tuesday.

On Friday, the United States restored sanctions waivers allowing international nuclear cooperation with Iran on projects designed to make it harder for Iran's nuclear sites to be used to develop weapons, although a senior State Department official said that was not a signal Washington was on the verge of reaching an agreement.

"The issue of removal of sanctions and Iran benefiting from it is Iran's red line in the talks," Saeed Khatibzadeh said.

"Washington has decided to take a step which has no impact on Iran's economic situation ... a responsible (U.S.) government should return to the deal and fulfill its obligations," he said.

Iran's Foreign Minister Hossein Amirabdollahian on Sunday described the U.S. move as "good but insufficient".
