In 1922, Ibn Saud and British officials representing Iraqi interests signed the Treaty of Mohammara, which established the boundary between Iraq and the future Saudi Arabia. Later that year, the Uqair Protocol signed by the two parties agreed to the creation of a diamond-shaped Saudi Arabian-Iraqi neutral zone of approximately 7,000 square kilometers, adjacent to the western tip of Kuwait, within which neither Iraq nor Saudi Arabia would build permanent dwellings or installations. The agreement was designed to safeguard water rights in the zone for Bedouin of both countries. In May 1938, Iraq and Saudi Arabia signed an additional agreement regarding the administration of the zone. Forty-three years later, Saudi Arabia and Iraq signed an agreement that defined the border between the two countries and provided for the division of the neutral zone between them. The agreement effectively dissolved this neutral zone.
