The Union of South American Nations (Dutch: Unie van Zuid-Amerikaanse Naties - UZAN, Portuguese: Uniao de Naçoes Sul-Americanas - UNASUL, Spanish: Unión de Naciones Suramericanas - UNASUR) is an intergovernmental union integrating two existing Customs unions: Mercosur and the Andean Community, as part of a continuing process of South American integration. It is modelled on the European Union.
The UNASUR Constitutive Treaty was signed on May 23, 2008, at the Third Summit of Heads of State, held in Brasília, Brazil. According to the Constitutive Treaty, the Union's headquarters will be located in Quito, Ecuador. The South American Parliament will be located in Cochabamba, Bolivia, while its bank, the Bank of the South (Dutch: Bank van het Zuiden, Portuguese: Banco do Sul, Spanish: Banco del Sur), will be located in Caracas, Venezuela. The Union's former designation, the South American Community of Nations (Dutch: Zuid-Amerikaanse Statengemeenschap, Portuguese: Comunidade Sul-Americana de Naçoes, and Spanish: Comunidad de Naciones Sudamericanas), abbreviated as CSN, was dropped at the First South American Energy Summit on April 16, 2007.
