TCU and the EFSUR
The Organization of Supreme Audit Institutions of MERCOSUL Countries and Associated

President Pro Tempore: Comptroller General of the Republic of Paraguay, Camilo Daniel Benítez Aldana.
Executive Secretary: Auditor General of the Argentine Republic, María Graciela de la Rosa.
The Organization of Supreme Audit Institutions of the MERCOSUR and Associated Countries (EFSUR), currently composed of SAIs of Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay, and Venezuela, is the result of a joint interest to follow up the acts carried out by the integration of the countries through the 1991 Treaty of Asunción, as well as the desire to exchange information and experiences of the institutions.
Likewise, the EFSUR defines actions on external control in the region through an internal body known as Joint Commission for Technical, Scientific, and Cultural Cooperation.
