President Donald Trump announced on Tuesday that the United States would withdraw from the Iran nuclear deal and renew trade sanctions that were eased during the Obama administration after years of negotiations.

China, the European Union, France, Germany, Russia and the United Kingdom also were parties to the agreement that Iran adopted in 2015, which is formally known as the Joint Comprehensive Plan of Action (JCPOA), and had agreed to lift some economic sanctions provided that Iran stopped certain aspects of its nuclear program. These other parties haven’t indicated they will join the United States in withdrawing from the JCPOA.
