Path Forward on Nuclear Deal Discussed in Vienna

Iran and world powers discussed the latest steps in ongoing efforts to offset the impact of US withdrawal from the 2015 Iran nuclear deal during a meeting in Vienna on Wednesday, which also intended to flesh out a newly established European mechanism to circumvent American sanctions.  
The meeting was the first convened by Iran and members of the Joint Commission—which is tasked with monitoring the implementation of the nuclear deal—since Europe set up INSTEX (Instrument in Support of Trade Exchanges) to conduct non-dollar trade with Tehran via a system that would help avert US penalties.   
Britain, France and Germany are parties to the Iran deal, as was the United States under ex-president, Barack Obama.
