Iran has renewed its rejection of the "step for step" principle regarding the return to the nuclear agreement, in conjunction with sending a delegation to Vienna to discuss the file, while demanding a regional dialogue to ensure the security of the region, and confirmed its readiness to settle its differences with Saudi Arabia.

Iranian Foreign Ministry spokesman Saeed Khatibzadeh said that his country would not accept any proposal on the nuclear file based on the "step for step" principle.

He added, "Our position on the need to lift US sanctions has not changed, and we demand that all of them be lifted."

He stressed that there is no need for direct or indirect negotiations with Washington to return to the nuclear agreement.

Zadeh explained that the Iranian negotiating delegation will travel to Vienna on Monday to continue negotiations and attend the meeting of the Joint Committee of the Nuclear Agreement.

Last week, world powers and Iran concluded a round of talks in Vienna, with the aim of returning the United States to the agreement from which former US President Donald Trump withdrew in 2018.

The tour also discussed Iran's return to compliance with the terms of the agreement, which it disavowed in response to the US position.

Earlier, Iranian President Hassan Rouhani commented on the negotiations of the previous round by saying that they were completed at a rate ranging between 60 and 70%. He said that the dispute could be resolved quickly if the United States acted "fairly".

On Sunday, Abbas Araqchi, the Iranian assistant foreign minister, revealed that there had been understandings regarding the lifting of sanctions related to oil, banks and financial transactions, but he did not provide more detailed information on these understandings.

Zone security

In another context, Zadeh said that the Israeli moves against his country will not remain without a response, and that Tehran will not allow Israel to destabilize the security of the region.

Zadeh indicated that the security of the region will only be achieved through regional dialogue, and that this is the only path that serves the interests of the countries of the region.

He also affirmed Tehran's adherence to its position to settle differences with Saudi Arabia through dialogue and negotiation, "if Saudi Arabia is ready."

Iran's call for a regional dialogue coincided with the visit of its Foreign Minister, Javad Zarif, to Doha on Sunday, where he conveyed to the Emir of Qatar, Sheikh Tamim bin Hamad Al Thani, an oral message from Iranian President Hassan Rouhani, related to bilateral relations between the two countries, means of supporting and strengthening them, and issues of common concern.

Zarif also met with Qatari Foreign Minister Sheikh Mohammed bin Abdul Rahman Al Thani, and the two sides discussed several files in Doha, including issues of common interest that concern the region.
