There’s lots of qualifying language from the Iran Deputy Foreign Minister that is primarily directed at a domestic audience, given recent public backlash in Iran against the negotiators—this is just some of it:
Iran’s deputy foreign minister says MoU with U.S. does not mean trust in the ‘enemy’.
Iran’s deputy foreign minister says Iran will monitor the implementation of U.S. commitments.
Iran’s deputy foreign minister says Iran will take our own measures if we witness breaches from the other side.
