Resumen
The Center of training for regional integration (CEFIR, in Spanish) was founded more than 20 years with the firm intention to dedicate efforts on issues of regional integration in the four countries of MERCOSUR.Since 2008 has promoted the creation of a platform for e-learning and delivered some courses in blended learning and e-learning mode, for training in regional integration issues.E-learning has become a transversal theme in the organization and became an efficient instrument for promoting regional integration of the 4 countries of the brick. The heterogeneity of countries, cultures and even languages raised a number of challenges when implementing the e-learning strategy.
