Since 2014, GPMG has embarked on a dynamic approach aimed at developing cross-border and transnational cooperation on the French Guiana Plateau. It is a question of streamlining and profitable trade between the countries of the zone, Brazil (Pará and Amapá) and Guyana in particular. DESCRIPTION OF THE PROJECT: The objective of this study is to examine the possibilities of implementing a maritime cabotage scheme to serve the various areas of port activities located on the coast of the Plateau des Guyanes, with two extensions: — maritime cabotage to the Caribbean. — a river-sea cabotage in Guyana with a length of about 300 km and the major rivers of Guyana. Note this draft has been extended and amended (during the written consultation of 11/09/18), in view of the success of its first phase, in order to: — Change the duration of the operations (end of 31/12/2019). — Draft and launch an AMII for the commissioning of the interregional cabotage line.
