The 1975 Algiers Agreement (commonly known as the Algiers Accord, sometimes as the Algiers Declaration) was an agreement between Iran and Iraq to settle their border disputes and conflicts (such as the Shatt al-Arab –known as Arvand Rud in Iran– and Khuzestan), and served as basis for the bilateral treaties signed on 13 June and 26 December 1975. This agreement was meant to end the disputes between Iraq and Iran on their borders in Shatt al-Arab and Khuzestan, but the main reason for Iraq is to end the Kurdish rebellion. Less than six years after signing the treaty, on 17 September 1980, Iraq abolished the treaty but under international law, one nation cannot unilaterally reject a previously ratified treaty, and the treaty had no clause providing for abrogation by one nation only.
