This map shows where Barack Obama and Dmitry Medvedev were in the same city at the same time during international trips in 2010.
Despite representing rival global powers, most real-time overlaps occurred at major international summits in places like Toronto, Seoul, Yokohama and Prague – reflecting the highly interconnected diplomatic landscape of the early 2010s.
Medvedev recorded approximately 129% more international visits than Obama in 2010, visiting 30 countries across 5 continents, compared to Obama’s 10 countries across 3 continents.
While Medvedev’s travel activity was broadly distributed globally, Obama concentrated 59% of his international visits in Asia, highlighting the growing strategic importance of the region during that period.
Both leaders shared 6 locations overall, but only 4 overlaps occurred during the same time window and are visualized on the map.
