No replacement plan exists, however, and worries persist that the political vacuum will result in renewed fighting. Morocco continues to propose autonomy for the territory as the solution to the conflict, while the Polisario Front insists on nothing other than complete independence. In 2006 the Moroccan Royal Advisory Council for Saharan Affairs (CORCAS) proposed a plan for the autonomy of Western Sahara and made visits to a number of countries to explain and gather support for their proposal. Citing the Spanish approach to regional autonomy, the Moroccan government plans to model any future agreement after the cases of the Canary Islands, Basque Country, Andalusia or Catalonia. The plan was presented to the UN Security Council in April 2007, and has received the backing of both the United States of America and France. On 30 April 2007, the United Nations Security Council passed Resolution 1754, which both urged the involved parties to "enter into direct negotiations without preconditions and in good faith." and extended the MINURSO mission until 31 October 2007. As a result of the passage of this resolution, the parties involved met in Manhasset, New York to once again try and settle the dispute. The talks between the Moroccan government and the Polisario Front were considered the first direct negotiations in seven years between the two parties, and hailed as a landmark in the peace process. Also present at the negotiations were the neighboring countries of Algeria and Mauritania, a nod to the role they play in the ongoing conflict. The first round of talks took place on 18–19 June 2007, during which 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. 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.
