Both the Biden administration and Iranian leaders say they want to revive the 2015 nuclear agreement. But they’re stalled over who should take the first steps — or make the first concessions — to get there.

This week European, Russian and Chinese partners in the agreement will mediate talks in Vienna to try to bring Iran and the U.S. back in. The talks officially start Tuesday and could take days or multiple rounds.

The U.S. State Department expressed guarded optimism in a statement Friday, saying, “These remain early days, and we don’t anticipate an immediate breakthrough as there will be difficult discussions ahead. But we believe this is a healthy step forward.”
