Accusing President Biden of constant “the thick file of the Trump sanctions towards Iran,’’ the brand new, hard-line Iranian overseas minister stated on Friday that in return for agreeing to limits on its nuclear program, his nation would demand much more sanctions aid than it obtained below the 2015 nuclear deal.

In two prolonged interviews with journalists throughout the United Nations Normal Meeting assembly in New York, his first as Iran’s high diplomat, Hossain Amirabdollahian stated that Iran would return “very quickly” to negotiations in Vienna. However Tehran, he stated, had obtained “contradictory messages” from Washington about restoring the settlement jettisoned by Donald J. Trump greater than three years in the past.

The overseas minister represents a brand new authorities that’s extra intently tied to the army and brazenly antagonistic to the West than its predecessor, and his repeated insistence on gaining extra advantages in return for returning to the deal factors to a looming deadlock with the USA.

American officers have stated that if Iran needs to see different sanctions lifted, it have to be ready for what Secretary of State Antony J. Blinken has described as a “longer and stronger” accord than the unique, which runs via 2030 — one that may considerably lengthen the time interval when Iran wouldn’t be permitted to carry greater than a token quantity of nuclear gas.

“We is not going to have a so-called ‘longer and stronger’ deal,’’ Mr. Amirabdollahian instructed The New York Occasions in an interview on Thursday night time at his resort reverse the United Nations headquarters. The 2015 accord “has a variety of harsh critics in Iran,” he stated, “however we accepted it.’’

American officers stated they weren’t shocked by Mr. Amirabdollahian’s place. Whereas they didn’t meet the brand new overseas minister — Iran’s supreme chief, Ayatollah Ali Khamenei, has banned direct contact — they stated he had made related statements to European leaders over the previous 5 days.

U.S. officers have been anticipating that the hard-liners in Iran’s new authorities would attempt to elevate the value for returning to the accord that Mr. Trump pulled out of in 2018. To realize leverage, over the previous two years Iran has resumed its manufacturing of uranium and now has a stockpile of gas far in extra of the bounds of the 2015 accord. Earlier this week, Britain’s overseas workplace declared that “Iran has by no means been this near being able to develop nuclear weapons.”

Consultants estimate that Iran might produce bomb-grade uranium in a month or two, however that it might take 18 months or extra to trend it right into a working weapon — loads of time for the USA, Israel and others to reply. However with every passing month, Iran has expanded its stockpile, and its data, about the way to enrich uranium, at scale, to a degree that may make it a so-called threshold nuclear energy — on the verge of possessing a nuclear weapon, however not fairly over that line.

Mr. Amirabdollahian’s rejection of any harder or prolonged nuclear settlement appeared to sign that Iran intends to protect the time-frame of the 2015 settlement, with restrictions on the quantity of nuclear gas it could possibly produce largely expiring in 2030. There may be growing concern within the West {that a} length that appeared lengthy sufficient in 2015 appears disturbingly brief in 2021.

The brand new minister portrayed his view of coping with the USA as dramatically totally different from that of his urbane, American-educated predecessor, Mohammad Javad Zarif, saying the earlier authorities had spent far an excessive amount of vitality negotiating prolonged, detailed agreements with the USA.

“The usual for us,’’ stated Mr. Amirabdollahian, “might be one to observe the motion of U.S. officers and choose primarily based on actions taken by President Biden,’’ slightly than on Mr. Biden’s “paradoxical statements.”

He recommended that the Iran deal went off the rails lengthy earlier than Mr. Trump took workplace. He argued that President Barack Obama had labored, even after the accord was reached, to maintain Iran from reaping the advantages of sanctions aid.

“It’s vital to notice that the violations started below Obama, after which President Trump,’’ he stated, contending that banks and vitality corporations pulled again from signing offers even when the settlement was in place.

He’s partly proper: Many corporations feared the principles would change once more after the 2016 presidential election. That concern proved warranted, as Mr. Trump rescinded the deal and imposed new sanctions.

The identical might occur once more, Mr. Amirabdollahian stated, so Iran is studying the way to stay in a world of sanctions. “We is not going to tie the destiny of our nation to the J.C.P.O.A.,’’ he stated, utilizing the formal title for the accord, the Joint Complete Plan of Motion.

“We are going to return to the negotiations and can accomplish that in a short time,’’ he instructed The Occasions. “But when our counterparts don’t change their habits we could not attain the required consequence.”

At a day by day information briefing, the State Division spokesman, Ned Value, sounded skeptical about Iranian speak of resumed negotiations.

“You’ll have to ask them on the that means of ‘quickly’ and ‘very quickly,’” Mr. Value stated. “That could be a message we’ve heard all week, however we have now up till this level not obtained readability on what exactly which means.”

Contained in the White Home and the State Division, there’s now an expectation that the talks might spill into subsequent 12 months, and will collapse totally. Talking at a information convention on Thursday as he wrapped up per week of diplomacy on the annual United Nations gathering, Mr. Blinken warned Iran, as he has repeatedly in current weeks, that point was operating out for a comparatively easy return to the 2015 nuclear settlement.

Uranium enrichment makes use of centrifuges to separate the frequent type of the aspect from the a lot rarer and extra radioactive isotope that may create a nuclear explosion. It turns into usable in a weapon when about 90 p.c or extra is the stronger kind. Underneath the 2015 settlement, Iran was restricted to enrichment to lower than 4 p.c, sufficient to gas a nuclear energy plant.

Mr. Blinken stated that “with each passing day, as Iran continues to take actions that aren’t in compliance with the settlement — notably constructing bigger stockpiles of extremely enriched uranium to twenty p.c, even to 60 p.c, and spinning sooner centrifuges” its nuclear program makes progress towards a degree past which it can’t simply be reversed.

Mr. Blinken and different Biden administration officers have repeatedly declined to say how a lot time stays, or what particular metrics they may use to evaluate that the 2015 framework can’t be salvaged.

He and the State Division’s envoy for Iran, Robert Malley, consulted with allies on the matter in New York this week, however departed with no particular date for a return to talks in Vienna. The issue of their activity was underscored by a fiery deal with to the United Nations on Tuesday by Iran’s new President, Ebrahim Raisi, who condemned the USA as a world bully.

In two conversations — one on Thursday night time with New York Occasions journalists and one other on Friday morning with a wider group of American reporters — Mr. Amirabdollahian declined a number of alternatives to clarify why Iran was now, for the primary time, producing nuclear gas that’s near bomb-grade. His aides stated that the manufacturing of the gas at 60 p.c purity was largely a political assertion, an indication that Iran deliberate to train all of its rights as a signatory of the Nuclear Nonproliferation Treaty — which allows it to provide the gas, however bars it from taking the final steps to show it right into a weapon.

However they famous that extremely enriched uranium may very well be utilized in naval reactors, suggesting they may need to use it for that objective. They usually cited Mr. Biden’s new cope with Australia, which requires the U.S. and Britain to provide Australia with the know-how for nuclear-propelled submarines, which use extremely enriched uranium. Australia is just not thought-about a proliferation risk, however to the Iranians that is largely proof of a double customary.

Mr. Amirabdollahian did supply one uncommon instance of concord with American diplomacy, calling on Afghanistan’s new Taliban authorities to guard the rights of non secular and ethnic teams. Iran’s Shia-led authorities has sought to guard Afghanistan’s Shiite Hazara minority, which suffered massacres by the hands of the Taliban when the Sunni militant group final ruled Afghanistan.

“We firmly imagine the one answer is the formation of an inclusive authorities, so as to push ahead,” Mr. Amirabdollahian stated of Afghanistan. “We have now been in touch with all sides.”
