Abstract

Despite representing a crucial day-to-day diplomatic tool, travel by heads of government and state (HOGS) has remained an under-investigated topic in international relations, inhibiting our ability to better understand how these visits change foreign aid, interstate conflict, diplomatic affinities, and more. Here, we fill that gap by introducing the first global dataset on the foreign visits of state leaders, the Country and Organizational Leader Travel (COLT) dataset, which allows us to present descriptive analysis and assess the monadic and dyadic drivers of foreign travel by HOGS. We find evidence consistent with previous literature explaining the motives of leader travel: development, trade, conflict, institutional co-membership, and regime type. In addition, we show a potential further application of the dataset, presenting original results on the relation between diplomatic visits and international trade. Overall, these data represent a unique indicator of international interaction that cuts across levels of analysis.
