Kuwait–Saudi Arabia relations are the relations between the State of Kuwait and the Kingdom of Saudi Arabia. In the aftermath of World War I, King Ibn Saud wanted to annex Kuwait into Saudi Arabia. Border conflicts were fought in 1919–1920, in which the Kuwaitis successfully fought them off with British assistance. Following the war the Saudis imposed a trade blockade on Kuwait from 1923 until 1937, which heavily impacted the Kuwaiti economy. The goal of the Saudi pressure was to annex as much Kuwaiti territory as possible. At the Uqair conference of 1922 which was convened to decide on the borders between some of the newly formed Arab states, Ibn Saud succeeded in persuading British diplomat Sir Percy Cox, the high commissioner in Iraq, to give the Saudis two-thirds of Kuwaiti territory.
