both parties agreed to resume talks on 10–11 August. After another inconclusive round of talks, the parties finally, on 8–9 January 2008, agreed on "the need to move into a more intensive and substantive phase of negotiations". An additional round of talks was held from 18 to 19 March 2008, but once again no major agreement was reached. The negotiations were supervised by Peter van Walsum, UN Secretary General Ban Ki-moon's personal envoy for Western Sahara. To date, all negotiations have failed to resolve the dispute. Peace talks resume In 2018 the United Nations Security Counsel announced that peace talks regarding the Western Sahara territory would resume and delegates of the Polisario Front, Morocco, Algeria, and Mauritania would all be present. In April 2020, the Polisario Front publicly condemned the state of the on-going peace talks stating that its inaction legitimized the encroachment of Morocco into the territory. The statement reiterated the Polisario Front's request that the UN organize a free referendum within Western Sahara on their self-governing status. Currently the position of United Nations envoy to Western Sahara is empty and the Security Counsel is actively seeking a replacement. On 6 October 2021, United Nations Secretary‑General, António Guterres, announced the appointment of Staffan de Mistura as his Personal Envoy for Western Sahara. On 13 January 2022, De Mistura commenced a round of discussions starting with Morocco's Foreign Minister, Nasser Bourita. On 15 January 2022, de Mistura, met with Polisario's head of political organization, Khatri Addouh, in Shahid Al Hafed. Current situation Polisario-controlled areas The Polisario controls about 20–25% of the Western Sahara territory, as the Sahrawi Arab Democratic Republic (SADR), and claim sovereignty over the entire territory of Western Sahara. SADR was proclaimed by the Polisario Front on 27 February 1976, in Bir Lehlu, Western Sahara. Polisario calls the territories under its control the Liberated Territories or the Free Zone, while Morocco controls and administers the rest of the disputed territory and calls these lands its Southern Provinces. The SADR government considers the Moroccan-held territory occupied territory, while Morocco considers the much smaller SADR held territory to be a buffer zone. In addition, the Polisario Front has a full autonomous control of the Sahrawi refugee camps. The refugee camps were set up in the Tindouf Province, Algeria in 1975–76 for the benefit of Sahrawi refugees fleeing from Moroccan forces during the Western Sahara War.
