On August 3, U.S. Secretary of State John Kerry joined a meeting of Gulf Cooperation Council (GCC) foreign ministers in Doha, Qatar, after which the Arab Gulf states unanimously and publicly endorsed the international nuclear agreement with Iran. The Joint Comprehensive Plan of Action (JCPOA), which promises Iran phased sanctions relief in exchange for limitations on its nuclear activities, was agreed to in Vienna on July 15 by Iran and the P5+1 international consortium, comprising the United States, Russia, China, the United Kingdom, France, and Germany. The Gulf countries had not been a party to the talks, and several of them had expressed official and unofficial concerns about the negotiations while they were ongoing. However, the joint statement released by the GCC foreign ministers and Kerry unified the Gulf position in favor of the agreement.
