Talks between Iran and world powers on reviving the 2015 Iran nuclear deal will resume in Vienna on Saturday, Iranian Deputy Foreign Minister Abbas Araqchi said on Friday.

"The participants are expected to continue consultations on the possible return of the United States to the nuclear accord and ensuring the full and effective implementation of this agreement," Araqchi, Iran's top negotiator at the talks, said on his channel on the Telegram messaging app.

In 2018, then-President Donald Trump pulled the US unilaterally out of the agreement saying that it was not broad enough and needed to be renegotiated. As part of a maximum pressure campaign, he re-imposed sanctions and added additional ones on Iran in an effort to bring Tehran back to the table.

Iran's economy was crippled by the move but it has refused new talks, instead retaliating by slowly and steadily breaking the restrictions of the JCPOA in an effort to pressure the other parties involved, thus far unsuccessfully, to come up with incentives to offset the American sanctions.

Biden, who was vice president when the original deal was negotiated, said he wants the US to rejoin but that Iran has to return to complete compliance.
