The three-way meeting in Beijing stood out for its effort to clarify the historical context of the Iranian nuclear issue and to present impartial, fair and equitable demands to all parties involved.

The Russia-Ukraine conflict raises uncertainties in negotiations for a renewed Iran nuclear deal. Thorny problems remain. But while there are negatives, there are also opportunities.

Both the United States and Iran want the other to make the first move. But even if the Biden administration were to lift sanctions tomorrow, international investors will not return to the Iranian market quickly. They fear a new Republican administration in the U.S. will scuttle the program again.
