In May 1974 , Iraq and Iran started a committee to mark the Shatt al-Arab boundary between them . In the 1974 Arab League summit , representatives from Iran 's government attended to talk with Iraqi representatives with the mediation of King of Jordan Hussein . Talks continued between the two countries sporadically , because Iraq was reluctant to give up his territorial demands . Iran started increasing its support of the Kurds , which led the Iraqi Army to fold . Saddam Hussein and Mohammed Reza Pahlavi attended the OPEC summit on 6 March 1975 in Algiers , where they agreed on an agreement and signed it with the mediation of Houari Boumédiène
