Iranian media, quoting a source it described as close to the Vienna negotiations, said that the United States had not yet taken a decision regarding the talks, accusing Washington of procrastination.
The Iranian news agency "IRNA" quoted this source as saying that a large part of the texts of the agreement were drafted, which is considered a remarkable progress in the negotiations.
The source added - to the agency - that if Western countries take the necessary decisions regarding lifting sanctions and nuclear files, the result can be reached in a very short period of time.
The eighth round of the Vienna negotiations between Iran and the 4+1 group started on the seventh of this month, and included statements from the participating parties that the negotiations had entered their final and decisive stages, and Washington's repeated demands to expedite an agreement.
And the Secretary of the Iranian National Security Council, Ali Shamkhani, had said - in previous statements - that the voices being heard from the US administration show that there is no internal harmony for making political decisions to move forward with the Vienna talks.
Tehran demands the lifting of all sanctions targeting it, and says that it has returned a clear program of action to Vienna, while the United States considers that the conclusion of the agreement has become an urgent matter.
Meanwhile, Chief of Staff of the Iranian Armed Forces Major General Mohammad Bagheri said that his country will continue to develop its missile capabilities.
Washington, under former President Donald Trump, unilaterally withdrew from the agreement in 2018, 3 years after its conclusion, re-imposing harsh sanctions on Iran, which responded almost a year later by gradually withdrawing most of its obligations under the agreement.
The current negotiations aim to allow Washington and Tehran to simultaneously return to abide by the agreement supported by current US President Joe Biden.
Russian-Iranian cooperation
In turn, the head of the Second Asia Department of the Russian Foreign Ministry, Zamir Kabulov, confirmed - earlier - that his country does not limit itself to the embargo imposed on Iran in matters of military and technical cooperation.
He revealed that the two countries are working to establish a mechanism to protect trade exchange and financial transactions between them from the risks of Western sanctions.
Kabulov added that the new Iranian leadership gave signals to Moscow that Russian companies will have the preference to invest in Iran after the lifting of sanctions.
