US, Russia Envoys Discuss Iran Nuclear Deal Ahead of Summit

VIENNA - Delegations from Russia and the United States involved in nuclear negotiations with Iran held talks in Vienna on Monday, two days ahead of a summit meeting between U.S. President Joe Biden and Russian President Vladimir Putin. 

The United States is not directly involved in the Vienna negotiations but has regular contacts with participating diplomats.  Efforts to revive a 2015 nuclear containment deal for Iran are a rare topic of collaboration between the two global adversaries.  Mikhail Ulyanov, a senior diplomat who headed the Russian delegation at the meeting in Vienna, called the talks with U.S. counterparts "fruitful."
