In the search for lasting solutions, a quadripartite consultative process was initiated in 2011, involving the Islamic Republics of Afghanistan, Iran and Pakistan and UNHCR. This led to the International Conference on the Solutions Strategy for Afghan Refugees to Support Voluntary Repatriation, Sustainable Reintegration and Assistance to Host Countries (SSAR), which was co-hosted by UNHCR and the government of Switzerland in May 2012. The conference endorsed both the solutions strategy and the establishment of follow-up mechanisms for implementation through the adoption of a joint communiqué.
