Abstract China’s strong economic presence in Africa has resulted in an increased interdisciplinary debate. Our contribution is the incorporation of a business perspective by uncovering the prominence and role of business in China’s diplomatic Africa engagement. Our theoretical contribution by applying the state-business relations (SBR) literature is to examine whether established frameworks can be expanded by an international dimension through intergovernmental initiatives like the Forum on China-Africa Cooperation (FOCAC). The paper conducts a document analysis of all declarations and Action Plans of all FOCAC conferences in the period 2000–2021, combining both a content and a thematic analysis based on an explorative and iterative coding process. Our data suggests that the prominence of businesses has increased while the scope of their activities and the number of focus sectors (especially infrastructure) has risen particularly since 2012. Companies are considered as enablers for political and economic goals in the state-driven FOCAC. We find that SBR frameworks are applicable to international contexts and propose an expanded SBR approach integrating transnational intermediary institutions like the intergovernmental FOCAC and transnational business platforms which facilitate positive state-business relations across countries and a conducive business environment.
