New analysis showed that world leaders are taking nearly double the number of overseas trips compared to three decades ago.
Whereas African leaders accounted for about a fifth of all such international travel from 1990 to 1994, that figure rose to 30% three decades later; Asian and Latin American leaders, by contrast, saw their relative share decline.
The data also illustrates how much borders have shifted: One of the earliest trips studied was by Czechoslovakia’s prime minister to East Germany, neither of which exist today; one of the latest was by Montenegro’s president to Azerbaijan, neither of which existed when the dataset began.
