“We are moving in the right direction and the atmosphere of dialogue is constructive and positive. But we must know that this will not be easy, so we will negotiate again and resume negotiations. The biggest obstacle to revive the JCPOA is that the United States is reluctant to lift sanctions imposed by the Trump administration,” Araghchi said.

“The United States must lift all sanctions imposed by Trump’s administration, not only those related to the nuclear deal. Our position is that if the United States wants to return to the nuclear deal, in addition to the sanctions related to the JCPOA, it must lift all sanctions imposed by the previous administration,” he added.

He also stressed that the best outcome would be a conclusion within five or six weeks, noting Iran's willingness to allow the International Atomic Energy Agency to inspect nuclear facilities to some extent until late May.
