Determinants of Leader Visits: A Review and Future Directions in Scholarship

Abstract

A recent surge in studies on high-level leader diplomacy has the potential to evolve into a fruitful research field. While the current literature predominantly focuses on the leader visits of two great powers, the U.S. and China, this emerging field requires both broadening and deepening in its scope. We lack data on leader visits from the vast majority of countries, and many existing hypotheses do not adequately explain the determinants in various cases. The more countries that are covered and the more refined our hypotheses become, the more insightful this field will be in understanding interactions among states and international organizations. This article aims to present the current state of the literature on leader visits and suggests potential areas of interest for future research.
