Return to Full JCPOA Compliance Hinges on Oil Sale Assurance

Iran demands firm guarantee for its oil sales to reverse the steps taken beyond the limits set in the international 2015 nuclear deal, a top diplomat said. 
Under the agreement, formally called the Joint Comprehensive Plan of Action, which was signed by six world powers, Iran placed curbs on its nuclear program in return for relief from international sanctions. 
The United States, however, unilaterally exited the deal last year and reinstated harsh sanctions, especially aiming for a complete halt to Iranian oil exports, the main source of the country's income.
