Iranian President Ebrahim Raisi said on Monday that talks in Vienna on reviving Tehran's 2015 nuclear deal with world powers cannot succeed unless the United States is prepared to lift sanctions on the Islamic Republic.
"The United States must prove its will to lift major sanctions," Raisi said in a joint news conference with Qatari Emir Sheikh Tamim bin Hamad al-Thani in Doha.
"To reach an agreement, guarantees are necessary for negotiations and nuclear issues," he said.
