Iran's foreign minister says the country’s demand to remove the Revolutionary Guards from the US list of foreign terrorist organizations is a "minor" issue in the negotiations to revive the 2015 nuclear deal.

Hossein Amir-Abdollahian said in a Thursday interview with CNN’s Fareed Zakaria at World Economic Forum’s annual meeting in the Swiss city of Davos that the Islamic Republic still considers the removal of Western economic sanctions as a key stumbling block in the Vienna talks to restore the Joint Comprehensive Plan of Action (JCPOA).

He said from Tehran’s point of view, the administration of President Joe Biden is continuing Donald Trump's maximum pressure policy, stressing the need to lift the Trump administration’s sanctions in order to see progress at the talks.

He said Iran is “keeping the window of diplomacy open,” noting that delisting the IRGC is not the main snag hindering a deal as long as Iran is guaranteed economic benefits.

“In fact, the IRGC being on the US blacklist of terrorist groups is a secondary issue that has been magnified by the pro-Israeli lobby and our main priority is the interests of the Iranian nation,” Iran’s top diplomat said.

“Now, we have reached a point that if the American side makes a realistic decision, an agreement would be within reach,” he said, adding that “Zionists do not want an agreement in the Vienna talks... Zionists tell many lies about Iran’s nuclear issue, but Americans know exactly what they must do if they want to return to the JCPOA.”

Amir-Abdollahian’s statement about IRGC’s terror listing as a minor issue contradicts remarks by Iranian officials who have said Tehran’s demand to delist the entity is “red line”.
