Looking at the Sunni religious networks in Iran, Stéphane Dudoignon shows how Iran is an interface between South Asia and the Gulf monarchies. This process went through the progressive building of a Sunni community of Iran, which is for the first time able to gather Sunnis from various ethno-national backgrounds. A recipient of Sunni influences from South Asia, the Shi‘a Islamic Republic, by coopting some influential Sunni religious leaders, has been able to re-export them to some Gulf monarchies, building for itself an unexpected form of Sunni soft power.
