When the United States lifted its sanctions, the Iranian centrifuge was the crux of the matter, because the election of Ebrahim Raisi put aside the negotiations.

A senior US official said on Thursday that if the serious differences between the two countries on resuming compliance with the 2015 nuclear agreement cannot be resolved in the “foreseeable future”, Washington may need to reconsider its attitude towards Iran.

“We still have serious disagreements on a series of issues, whether it is what nuclear measures Iran needs to take to regain compliance, the sanctions relief that the United States will provide, or the series of steps that both sides will take,” the official said in a conference call Tell reporters.

“This process will not be open forever,” the official, who asked not to be named, added.

“We do have differences, and if we cannot bridge them in the foreseeable future, I think we will have to regroup and figure out how we… move on.”

The sixth round of indirect talks between the United States and Iran was adjourned on Sunday. Two days ago, Iran’s Attorney General Ibrahim Raisi, who was sanctioned by the United States, was elected Iran’s president. Raisi will take office in August.

The official stated that the U.S. delegation is expected to return to Vienna for the seventh round in the near future, but he does not know when-hinting The key factor It will be Iran’s internal consultations after Raisi’s election.

Iran reached an agreement with major powers in 2015 to curb its uranium enrichment program, which is a possible way to obtain nuclear weapons in exchange for the lifting of sanctions by the United States, the European Union and the United Nations.

Former U.S. President Donald Trump Abandoned the deal The re-imposition of severe sanctions in 2018 prompted Tehran to begin violating certain nuclear restrictions in 2019 while maintaining its ambitions of no nuclear weapons. US President Joe Biden is seeking to restore the agreement.

Senior U.S. officials declined to elaborate The crux of the negotiationThis is indirect, because Iran refuses to sit down with the United States. European diplomats are the main intermediaries.

An official involved in the talks stated that Iran’s use of a large number of advanced centrifuges for enrichment is an unresolved issue, as is Iran’s request to “verify” US compliance before containing its nuclear program.

The official said that verification means Relaxation of U.S. sanctions, Before Tehran took steps to reduce its planned nuclear weapons capabilities, Iran exported some oil and paid for it through an international bank.

According to the 2015 agreement, Iran is only allowed to use advanced centrifuges in small quantities and cannot accumulate enriched uranium.

A Western diplomat agreed that there was a major obstacle in the sequence of steps, and the Iranians demanded immediate access to U.S. dollars and international banking.

The Western diplomat also said that advanced centrifuges that can produce highly enriched uranium more efficiently are a sticking point, and hinted that Iran might be allowed to keep some of them.

On June 23, the U.S. Department of Justice unexpectedly 36 websites seized For participating in “false propaganda activities and malicious influence operations” and the Iranian state, which aroused rapid criticism from Iranian officials.

The Iranian Ministry of Foreign Affairs described the seizure as an example of “a systematic effort to distort freedom of speech and suppress independent media voices on a global scale,” adding that Iran will resolve the issue through legal channels.
