More negotiations are expected to follow between Washington and Tehran following Friday’s signing ceremony in Switzerland, Iran’s Foreign Minister Abbas Araghchi has said, according to Al Jazeera.

Speaking after a meeting with members of the Iranian parliament’s Economic Commission, Araghchi cautions that negotiators are moving ahead amid a backdrop of distrust.

“We plan the process of negotiations and implementation of the agreement based on distrust, breach of commitments, and past experiences,” he says. “We try to create economic breakthroughs for the country as much as we can through the agreement.”
