The multifaceted relationships between domestic public opinion and geoeconomics are an increasingly salient feature of world politics. This chapter first details four common roles of public opinion in geoeconomics: (1) supporting and incentivizing economic statecraft; (2) implementing economic statecraft; (3) initiating economic punishments against foreign targets; and (4) responding to foreign economic statecraft. The second section provides an overview of recent research on public attitudes toward economic statecraft in both sending states (seeking to utilize economic statecraft) and receiving countries (targeted by such measures). The third section explores the further research needed to understand the role of publics in geoeconomic competition in an era of unprecedented cross-border interaction.
