This paper mobilizes the advocacy coalition framework (ACF) to examine the policy shift towards the diaspora, which was long perceived as a threat to Cameroon’s security and stability by government authorities and, since the mid-2000s, has become an actor to be mobilized for the country’s socio-economic development. It appears that ACF is applicable to policy changes in an African state characterized by a relatively unstable political context. Our analysis, which is based on a survey of civil servants, experts, and professionals, shows that political learning can have an impact on the fundamental beliefs of a coalition.
