VIENNA (Reuters) – Iran is not “a willing partner” in indirect talks on reviving the 2015 Iran nuclear deal, officially called the Joint Comprehensive Plan of Action, the United States told a meeting of the U.N. nuclear watchdog’s Board of Governors on Tuesday. “We stand ready to quickly implement a deal on a mutual return to full implementation of the JCPOA. What we lack is a willing partner in Iran,” the U.S. statement to the International Atomic Energy Agency’s 35-nation Board of Governors meeting said.
