DUBAI (Reuters) - Iran believes that barriers to the revival of its 2015 nuclear accord with world powers are complicated but not insurmountable, a spokesman said on Tuesday, denying that negotiations had stalled.

The Islamic Republic and six powers have been negotiating in Vienna since April to work out steps for Tehran and Washington to take, respectively, on nuclear activities and sanctions, for the pact to resume.
