Argentina's plan to privatize the Paraná-Paraguay waterway for 25 years, the country's main fluvial artery, is nearing its final stage. Two Belgian companies, Jan de Nul and DEME, are the finalists. However, the tender process is facing political questions regarding its design, the local partners involved, and the technical documentation. The National Ports and Navigation Agency (ANPyN) is managing the process, which the government sees as a major privatization. Jan de Nul, in partnership with Servimagnus, scored higher than DEME in the technical evaluation. DTA Engenharia, a Brazilian competitor, was disqualified. The opening of economic bids is expected soon. The concession will be awarded based on tolls, without state guarantees, and at the operator's risk. Controversy surrounds the process, with opposition lawmakers raising concerns about a technical report. The government states that the UN Conference on Trade and Development (UNCTAD) audited the procedure. The Argentine Port Council and the Office of Administrative Investigations have also raised objections. An investigation by Ámbito Financiero alleged that the Neuss Group had agreed to take a 50% share.
