In February 1989, North Yemen joined Iraq, Jordan, and Egypt in forming the Arab Cooperation Council (ACC), an organization created partly in response to the founding of the Gulf Cooperation Council and intended to foster closer economic cooperation and integration among its members. After unification, the Republic of Yemen was accepted as a member of the ACC in place of its YAR predecessor. In the wake of the Persian Gulf crisis, the ACC has remained inactive. Yemen is not a member of the Gulf Cooperation Council mainly for its republican government.
