The Craiova Group is a cooperation project of three European states – Romania, Bulgaria and Serbia – for the purposes of furthering their European integration as well as economic, transport and energy cooperation with one another. The Group originated in a summit meeting of the heads of governments, held on 24 April 2015 in the Romanian city of Craiova. Romania and Bulgaria both joined the European Union on 1 January 2007, while Serbia has been in accession negotiations since January 2014.
