===1991 Gulf war===

{{See also|1991 Persian Gulf war}}In 1990-91, Saudi Arabia played an important role in the Gulf War, developing new allies and improving existing relationships between Saudi Arabia and some other countries. Saudi Arabia provided water, food, shelter, and fuel for coalition forces in the region. Saudi Arabia's combined costs in payments, foregone revenues, and donated supplies were $55 billion. More than $15 billion went toward reimbursing the United States alone. However, there were also diplomatic and financial costs. Relations between Saudi Arabia and Tunisia, Algeria, and Libya deteriorated. Each country had remained silent following Iraq's invasion of Kuwait but called for an end to the violence once the deployment of coalition troops began. Relations between these countries and Saudi Arabia have returned to their pre-war status. Saudi Arabia's relations with those countries which expressed support for Saddam Hussein's invasion of Kuwait—Yemen, Jordan, and Sudan—were severely strained during and immediately after the war. For example, several hundred thousand Yemenis were expelled from Saudi Arabia after the Government of Yemen announced its position, thus exacerbating an existing border dispute. Saudi-Yemeni relations, especially in the wake of the 1994 Yemeni civil war, remained fragile and of significant concern to the Saudi Government. Relations have slowly warmed over time, and the Yemeni-Saudi border was finally demarcated in 2000. The Palestine Liberation Organization's support for Iraq cost it financial aid as well as good relations with Saudi Arabia and other Gulf states. Recently, though, Saudi Arabia's relations with Jordan and the Palestinian Authority have improved, with the Saudi Government providing assistance for the Palestinian Authority.
