Western powers and Russia have for almost a year worked closely to revive the 2015 Iran nuclear deal, but the war in Ukraine is creating a sense of urgency to conclude talks before cooperation becomes impossible.

It could also see more harsh sanctions on Iran by the West and continued upward pressure on world oil prices already strained by the Ukraine conflict.
