VIENNA, AUSTRIA - APRIL 06: In this handout provided by the EU Delegation in Vienna, Representatives of the European Union, Iran and others attend the Iran nuclear talks at the Grand Hotel on April 06, 2021 in Vienna, Austria. Representatives from the United States, Iran, the European Union, Russia, China and other participants from the original Joint Comprehensive Plan of Action (JCPOA) are meeting directly and indirectly over possibly reviving the plan. The JCPOA was the European-led initiative by which Iran agreed not to pursue a nuclear weapon in exchange for concessions, though the United States, under the administration of former U.S. President Donald Trump, abandoned the deal and intensified sanctions against Iran.
