The paper systematically reviews ten years of academic literature published from 2014 to 2023 and indexed in the Scopus database to establish the current state-of-the-art on how Central European regional groups operate. The review includes 52 publications on six regional cooperation formats: the Central European Defence Cooperation, the Slavkov/Austerlitz Triangle, the Salzburg Forum, the Three Seas Initiative, the Visegrád Group and the Bucharest Nine. The paper finds that regional cooperation research is very concentrated on selected aspects of Visegrád cooperation and follows poor methodological reporting practices. The majority of studies analyse the V4 in relation to migration and foreign policy issues, whereas research on cooperation dynamics in other policy areas and within other active regional groups is marginal. After identifying promising future research directions, the paper calls for greater methodological and topical diversity in Central European regional cooperation research.
