The neoliberal model adopted in Argentina during the 90s radically changed the role of the state in the provision of public utilities, inaugurating a new market-led model of infrastructure development. After the 2001 crisis, the model as theoretically conceived came to a halt which at the international level notably led to Argentina being the country with the most cases before the ICSID. In domestic politics, this meant that the need to continue to develop infrastructure to serve a growing population met the limits of a formal framework which was inapplicable in the books. Infrastructure development had to be reconfigured on a new foundation for which another “international” discourse became crucial. The place that was used in the past by the neoliberal speech came to be filled (at least partially) by the international human rights discourse. The argentine case serves to illustrate the tensions that arise from the clash of two dominating discourses at the international level.
