“Iran’s proposals to the world powers cannot be rejected. They are based on the provisions of the 2015 agreement,” Baqeri Kani, who serves as Iran’s Deputy Foreign Minister for Political Affairs, told Al Jazeera news channel on Friday, referring to the nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA).

He added that Tehran would deliver a third proposal once the first two were accepted.

Regarding the details of the proposed drafts on the removal of sanctions and nuclear issues, Baqeri Kani said the important point is that the two parties agreed on the foundation of negotiations which is the same nuclear deal of 2015.

“What we have presented is the malfunctions and the blunders which were in the text of the [JCPOA] draft and we presented some modifications,” the Iranian chief negotiator added.

He emphasized that all nuclear-related sanctions that the US imposed on Iran following its unilateral withdrawal from the JCPOA three years after its conclusion should be removed immediately.

Diplomats from the G4+1 countries gathered in Vienna on Monday for the seventh time, after a hiatus in the talks because of presidential election in Iran. Five days of intensive talks ended on Friday after the sides returned to the capitals for more consultations.

Baqeri Kani announced Thursday that Iran has submitted two proposed drafts to the other parties concerning the removal of sanctions and Tehran’s nuclear commitments, and is about to put forward a third draft.

The website of Iran’s Supreme National Security Council (SNSC) said on Friday that the Europeans’ lack of initiative in the face of the Iranian team’s “groundbreaking” proposals is dragging down negotiations in Vienna.

Iran’s top security body quoted Baqeri Kani as saying, “The first document sums up the Islamic Republic’s point of view concerning the removal of sanctions, while the second is about Iran’s nuclear actions.”

“In the third document to be presented to the other parties, Iran will state its views and proposals with regard to the verification period of removing sanctions,” he added.

The top Iranian negotiator also told reporters before his departure that the country’s new delegation to this round of talks was comprised of economic, financial and banking experts and officials, which “showed the Islamic Republic’s determination to enter the negotiations with the purpose of achieving an agreement.”

Speaking to reporters on Friday before leaving the Austrian capital for Tehran, Iran’s lead negotiator said the G4+1 group of countries has been given the chance to consult with their capitals on the Islamic Republic’s two proposed drafts, underlining that Tehran expects a “reasonable, documented and rational” response.

“It was emphasized that the proposals of the Islamic Republic of Iran on the removal of illegal and oppressive sanctions and the nuclear issue are on the table,” Baqeri Kani said.

“Since the opposite side needed to consult with their capitals to provide a documented and reasonable response to these proposals, it suggested that the talks be suspended for a few days.”

The senior Iranian diplomat noted that a new round of negotiations between the two sides would resume in the middle of next week.

The JCPOA was abandoned by former US President Donald Trump in May 2018. Trump then targeted Iran’s economy with what he called the “maximum pressure” campaign, but he failed to compel Iran to negotiate a “new deal”.

Iran and the five remaining parties to the JCPOA, Britain, France, Germany, Russia and China, began the talks in the Austrian capital in April with the aim of removing Washington’s unlawful sanctions against the Islamic Republic after the US voiced interest to return to the agreement.
