Since its formation, a key part of the Studienvereinigung's work has involved issues of European and international competition law. It organises regular working meetings in Brussels and engages in intensive dialogue with the European Commission.

For many years, the Studienvereinigung Kartellrecht has organised an international forum at the seat of the European Commission in Brussels, held every two years. Working meetings are also regularly held at the European courts in Luxembourg. In addition, the Studienvereinigung maintains close relationships with other organisations, for example the Section of Antitrust Law of the American Bar Association, the Antitrust and Trade Law Section of the International Bar Association, the AFEC and others. 

From time to time the Studienvereinigung organises joint events with other competition law organisations. The Studienvereinigung Kartellrecht acts as co-organiser of such events, and is responsible for chairing individual presentations as well as providing speakers.
