The weakness of Brazilian infrastructure is recognised by the government, which since the mid-1990s has undertaken important institutional and regulatory reforms in the infrastructure sectors, and from the mid-2000s introduced various federal and state programmes. Governments at the federal and state levels have also introduced various tax and credit incentives to increase private investment in infrastructure. Other activities include the development of electronic systems to facilitate the control of shipments in ports and other border points, and financial support for private and public storage.
