Can you think of any deal those 3 could make that would be beneficial to all 3 parties over the current status quo? You can ignore political feasibility
I certainly cannot, and in most situations political feasibility is the largest impediment
I think a big obstacle is Trumping wanting Iran to give its enriched uranium to the US for storage. Europe, China, and Russia would be open to it being stored in their countries or Pakistan. Iran trusts these 3 countries more. Also, China and Russia are allies of Iran and can pressure it into an agreement.
