The Craiova Group is a cooperation project of four European states – Romania, Bulgaria, Greece 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. At the group's inaugural meeting, Romania's then-Prime Minister Victor Ponta indicated that he was inspired by the Visegrád Group. Romania and Bulgaria both joined the European Union on 1 January 2007, while Serbia has been in accession negotiations since January 2014. Since October 2017 at the meeting in Varna, Bulgaria, with the inclusion of Greece, meetings have been quadrilateral. 
One of the first initiatives, after a meeting in Vidin, Bulgaria, was to strengthen the telecommunication networks in the border areas of the countries. Other goals include helping Serbia join the European Union and the construction of a motorway linking Bucharest, Sofia and Belgrade.
