The Treaty of Amity, officially titled the Treaty of Amity and Economic Relations and Consular Rights between Iran and the United States, was signed in Tehran in 1955. This agreement formalized the relationship between the two nations, reflecting the extensive economic, military, and political ties that existed before the Islamic Revolution during the Pahlavi era. The treaty aimed to foster lasting peace and genuine friendship by promoting trade, commercial activities, and the facilitation of consular and customs rights. Following its ratification, both American individuals and entities began investing in Iran. In the realm of international disputes, legal mechanisms such as international arbitration and courts are utilized to resolve conflicts, guided by international law.
