The Persian Gulf crisis dramatically affected Yemen's foreign relations. As a member of the UN Security Council (UNSC) for 1990 and 1991, Yemen abstained on a number of UNSC resolutions concerning Iraq and Kuwait and voted against the "use of force resolution". Western and Persian Gulf Arab states reacted by curtailing or canceling aid programs and diplomatic contacts. At least 850,000 Yemenis returned from Saudi Arabia and the Persian Gulf.
