The file concerns the possibility of establishing an international Conservancy Board for the Shatt-el-Arab (also referred to as the Shatt-al-Arab) between the governments of Iraq, Iran (also referred to as Persia), and the United Kingdom.

The board was intended to ensure the efficient maintenance and navigation of the Shatt-al-Arab waterway. The United Kingdom was involved because of the close interests of British shipping in the conservancy of the Shatt-al-Arab.

The papers cover: Perso-Iraqi frontier negotiations; drafts, signing (July 1937), and ratification (June 1938) of the Perso-Iraqi Frontier Treaty; Turkish approval of the frontier negotiations; the signing of the four power non-aggression pact between Iraq, Iran, Turkey, and Afghanistan (the Saad-Abad [Saadabad] Pact), 1937; Abadan anchorage; Foreign Office memoranda and minutes of meetings concerning a convention for the conservancy of the Shatt-al-Arab; the question of British participation in the convention; lighting and buoying; the involvement of Sir John Ward [serving with the Iraqi Government] in the discussions; the opposition of the Iranian Government to British involvement; the involvement of the Anglo-Iranian Oil Company (AIOC); the Port of Basra (including Foreign Office memorandum, folios 77-83); the Rooka Channel; and renewed discussion of the issue in 1945, including the importance of the Shatt-al-Arab for tanker traffic to supply Britain's war needs in the Far East.
