Prior to the 1990s there was a wide cooperation between pioneer and similar movements of about 30 countries, coordinated by the international organization, International Committee of Children's and Adolescents' Movements (French: Comité international des mouvements d'enfants et d'adolescents, CIMEA), founded in 1958, with headquarters in Budapest, Hungary.
Før 1990'erne var der en høj grad af samarbejde mellem pionerbevægelsen og lignende bevægelser i omkring 30 lande, koordineret af en international organisation, International Committee of Children's and Adolescents' Movements (fransk: Comité international des mouvements d'enfants et d'adolescents, CIMEA), grundlagt i 1958, med hovedkvarter i Budapest.
