The United Nations has attempted to mediate claims to the Western Sahara, with settlers being a major area of contention. In the early 2000s, UN Secretary General Kofi Annan
's Personal Envoy to the Western Sahara, James Baker, held multiple meetings with Moroccan and Polisario officials to discuss the future of the Western Sahara. They were ultimately ineffective and inflamed relations. Baker also put forth two peace plans that would introduce a four-year phase of autonomy to the Western Sahara and then put independence to a referendum-style vote. At either point, either the Polisario Front or Morocco denied the plan.
