The Government published Decree 427/2021 which establishes that the General Administration of Ports (AGP) will be in charge of the operation concession for the maintenance of the signalling system and dredging tasks as well as the hydrological control of the Paraguay-Paraná Waterway. The decree set a 12-month term for the provision of the service by the AGP, which can be extended. It will have to establish procedures for the eventual revision of tariffs or tolls, and specify the plan of works to be carried out as well as the technical parameters for their execution. The concession of the waterway has been in the hands of the Belgian company Jan de Nul since 1995 and expired on 30 April 2021. A 90-day extension was established to begin the process of defining the modality of operation, but the death of the then Minister of Transport, Mario Meoni, delayed the process. The current Minister of Transport, Alexis Guerrera, affirmed that from now on the process of calling for tenders for the maintenance of the waterway would begin. The political opposition warned that the nationalisation of the waterway, which is being promoted by a sector of the ruling party, could have a negative impact on the "value of the products" that circulate through this navigable channel, as it would imply an "increase in the toll" charged to vessels that work, above all, for the agro-export sector.
