RegioTriRhena e.V. sees itself as a network for strengthening the cross-border economy in the border triangle Freiburg – Colmar – Mulhouse – Basel. It was founded in 1995 on the initiative of the three Regio companies in Basel, Mulhouse and Freiburg in Breisgau and was reconstituted as a registered association under German law in 2003.
The aim is to strengthen the tri-national region on the southern Upper Rhine in order to better compete with other regions. To network the economy in the border triangle, the association organizes several company visits each year to innovative companies from all sectors in southern Alsace, southern Baden and north-western Switzerland. In addition, RegioTriRhena organizes a major annual conference once a year, which brings together experts from France, Germany and Switzerland to discuss current topics.
