The regional associations, in particular, are united under the English-French Challenge Camerounais. “Challenge” started in Bielefeld in 1991 with a football tournament that has been held annually ever since, at a different location each year. These matches are on their way to becoming the major sport and cultural event of the Cameroonian diaspora. The common interest in football plays an important role in integrating Cameroonians within the diaspora community. Some 3,000 Cameroonians attended the last match in Münster in June 2019, and record numbers are expected for the next one, in 2020 in Marburg. Also as part of “Challenge” activities, a Cameroon business forum was established in 2005 to foster contacts within the business community, and this has been an integral part of the programme ever since. A further development by the association is the formation of a business network to coordinate business activities and a Cameroonian diaspora network to link Cameroonian associations that are currently in the formation process. The aim of all of these networks is to support and shape development policy and/or private sector cooperation.
