of the Constitution." As of 2016, Tanzania is divided into thirty-one regions (mkoa), twenty-six on the mainland and five in Zanzibar (three on Unguja, two on Pemba). In 2012, the thirty former regions were divided into 169 districts (wilaya), also known as local government authorities. Of those districts, 34 were urban units, which were further classified as three city councils (Arusha, Mbeya, and Mwanza), nineteen municipal councils, and twelve town councils. The urban units have an autonomous city, municipal, or town council and are subdivided into wards and mtaa. The non-urban units have an autonomous district council but are subdivided into village councils or township authorities (first level) and then into vitongoji. The city of Dar es Salaam is unique because it has a city council whose area of jurisdiction overlaps three municipal councils. The mayor of the city council is elected by that council. The twenty-member city council is composed of eleven persons elected by the municipal councils, seven members of the National Assembly, and "Nominated members of parliament under 'Special Seats' for women". Each municipal council also has a mayor. "The City Council performs a coordinating role and attends to issues cutting across the three municipalities", including security and emergency services. The city of Mwanza has a city council whose areal jurisdiction overlaps two municipal councils. Foreign policies and partnerships Foreign Policies of Tanzania are in process of review to replace the current New Foreign Policy of 2001, which was the first official foreign policy of Tanzania. Before 2001, Tanzanian foreign policy was dictated by the various presidential declarations of Mwalimu Nyerere specifically Circular No. 2 of 1964, Arusha Declaration, and Policy of Foreign Affairs of 1967. These declarations had focused foreign policy primarily on independence and sovereignty, human rights, and African unity. The current New Foreign Policy of 2001 was established to better address the end of colonialism and the cold war, globalization, market economics and liberalization, and the multi-party state of Tanzania. Its primary focus is economic diplomacy and development. New Foreign Policy of 2001, which is still used today, has a foundation of 7 principles; sovereignty, liberalism, good neighborliness, African unity, non-alignment, economic diplomacy, and global cooperation for economic development and peace. The primary objectives are outlined as the protection and promotion of cultural and economic interests, establishment of relations with other nations driven by economic interest, economic self-sufficiency, internal and global peace, and regional
