In case of disagreement, these issues will be resolved through diplomatic channels. Article II. In order to establish the facts, border commissioners and their assistants may, on the basis of prior agreement, conduct joint investigations into border incidents on the spot. On this occasion, they may be accompanied, if necessary, by experts, interpreters and witnesses, as well as victims of the incident. Such an investigation shall be carried out by the Contracting Party in who who who its territory is located. In May 1974, Iraq and Iran began to mark the border between them. Iranian government officials attended the 1974 Arab League summit to meet with Iraqi officials, through King Hussein of Jordan.  Discussions between the two countries continued sporadically and Iraq hesitated to give up territories that had been allocated to it by the 1937 treaty. Iran has stepped up its support for the Kurds, which has greatly exacerbated the problems of the Iraqi army. Saddam Hussein and Mohammad Reza Pahlavi participated on March 6, 1975 in the OPEC summit in Algiers, where an agreement was reached and signed under the aegis of Houari Boumédiène, then president of the Algerian Revolutionary Council. In the event of an incident, the Border Commissioners shall jointly investigate by mutual agreement and record the results in a report. This addendum is part of the Treaty on State Borders and Neighbourly Relations between Iran and Iraq, signed in Baghdad on 13 June 1975, and is ratified at the same time as that Treaty. The conclusions and recordings of these meetings shall be communicated to the higher authorities of each of the two parties.
In the event of disagreement between the border authorities, the heads of the administrations concerned meet either in Baghdad or tehran to agree on positions and report on the results of their meetings. .
