Arrabona EGTC was set up by two Hungarian cities, Győr and Mosonmagyaróvár, in the Szigetköz and Csallóköz regions, and the Slovakian municipalities of Dunajská Streda and Šamorin. Today, the EGTC has 35 members (seven municipalities from Slovakia and 28 from Hungary).

The grouping is situated in the Budapest-Vienna-Bratislava axis region, which is one of the most dynamically developing metropolitan regions in central Europe. The economic mainstay of the region are the automotive and ancillary industries, including metalworking and metal-processing (Audi, VW and their suppliers.)

Győr and Bratislava serve as regional metropolises, where urban and rural tourism can develop in symbiosis. A cross-border tourist region could be established through effective destination management.

This has been the objective over the past few years, with a particular focus on the development goals of the municipalities concerned, while also considering cooperation with other partners (Cultacross and Builcogreen projects). In addition to cultural and tourist cooperation, the EGTC prioritises equal sharing of management tasks between its municipalities, so as to provide a unique, exemplary practice in the border region.
