The boundary with Iran, 959 km (595.9 mi), was first delimited by a British commission in the same year as the Durand Line was demarcated, separating Iran from what was then British India's Baluchistan province.[1] Modern Iran has a province named Sistan va Baluchistan that borders Pakistan and has Baluchis in an ethnic majority. In 1957 Pakistan signed a frontier agreement with Iran in Rawalpindi according to which the border was officially declared and the two countries haven't had this border as a subject of serious dispute at all.
