The Iranian government rejects the gradual lifting of sanctions and wants the United States to ease all the restrictions at once, an Iranian state broadcaster reported Saturday.
The two countries said Friday they would hold indirect talks in Vienna from next week as part of broader negotiations to revive the 2015 nuclear deal between Tehran and global powers. The U.S. State Department said the focus would be on "the nuclear steps that Iran would need to take in order to return to compliance" with that agreement.
Iranian Foreign Ministry Spokesperson Saeed Khatibzadeh said on Saturday that Tehran was opposed to any gradual easing of sanctions.
"No step-by-step plan is being considered," Khatibzadeh told Press TV. "The definitive policy of the Islamic Republic of Iran is the lifting of all U.S. sanctions."
The aim of the talks in the Austrian capital is to reach an agreement within two months, according to a senior official with the European Union, the coordinator of the deal.
Former U.S. President Donald Trump pulled out of the nuclear pact in 2018 and reimposed sanctions on Iran, prompting Tehran to breach some of the accord's nuclear restrictions.
Trump's successor Joe Biden wants to revive the agreement but Washington and Tehran have been at odds over who should take the first step. Biden said that the U.S. will not lift sanctions against Iran unless the Islamic Republic adheres to its commitments under the nuclear deal.
Iran, China, Russia, France, Germany and the United Kingdom – all parties to the 2015 deal – held virtual talks on Friday to discuss the possible return of the U.S. to the accord.
