Iran’s government wants the US to lift all sanctions against it and opposes any “step-by-step” relaxation of the restrictions, according to Iranian state broadcaster Press TV.

The two countries announced on Friday that indirect talks would begin next week in Vienna as part of wider talks to resurrect the 2015 nuclear agreement between Iran and world powers. The priority, according to the US State Department, would be on “the nuclear measures that Iran would need to take in order to return to compliance” with the deal.

Iranian foreign ministry spokesman Saeed Khatibzadeh said on Saturday that Tehran was opposed to any gradual easing of sanctions.

“There will be no step-by-step plan,” Khatibzadeh told Press TV. “The Islamic Republic of Iran’s definitive stance is the lifting of all US sanctions.”

According to a senior official with the European Union, the deal’s coordinator, the aim of the talks in Vienna is to find an agreement within two months.

In 2018, former US President Donald Trump withdrew from the nuclear agreement and re-imposed sanctions on Iran, causing Tehran to violate some of the agreement’s nuclear restrictions.

Joe Biden, Trump’s successor, wants to resurrect the deal, but the US and Iran are at odds about who should take the first step.

Iran, China, Russia, France, Germany, and the United Kingdom – all signatories to the 2015 agreement – held virtual talks on Friday to discuss the possibility of the US rejoining the agreement.
