A long-standing dispute between Saudi Arabia and Yemen was resolved in June 2000 with the signing of the Treaty of Jeddah. This agreement provides coordinates for use in delineating the land and maritime border, including the section in the eastern desert region of Yemen that potentially contains significant amounts of oil. Friction between the two countries in recent years over security of the borders appears to have been alleviated by the establishment of joint border patrols. Following years of dispute between Yemen and Eritrea over ownership of the Hanish Islands and fishing rights in the Red Sea, in 1999 an international arbitration panel awarded sovereignty of the islands to Yemen. Relations between the two countries remain strained, however, and Yemen continues to protest Eritrean fishing in the disputed territory.
