The main outcome of the higher level of trade between Europe and Asia has been a rapid rate of growth in sea container traffic, which could lead to congestion in Antwerp seaport. In order to address this risk Antwerp has naturally sought to conclude agreements with the Port of Liege, located within Antwerp's natural hinterland. The aim is quite straightforward: developing effective cooperation between the Port of Antwerp and the Port of Liege so as to guarantee a seamless system of distribution downstream from the port cargo unloading system. This is why the Antwerp port authorities immediately agreed to join forces with the Liege Port Authority and the SPI+ in early 2006 as part of an Economic Interest Grouping (EIG) designed to further the development and marketing of the future Liege Trilogiport multimodal platform.
