Arab League–Iran relations
The dynamic between the League of Arab States and the Islamic Republic of Iran has been ambivalent, owing to the latter's varying bilateral conduct with each country of the former. Iran is located on the easternmost frontier of the Arab League, which consists of 22 Arab countries and spans the bulk of the Middle East and North Africa, of which Iran is also a part.
