“The World Leaders on Instagram study also found that 156 of the 193 United Nations member states maintain an official Instagram account, 16 more than in the 2017 study. Ninety-two heads of state, 48 heads of government and 36 foreign ministers maintain personal pages on the platform, which tend to get better engagement than institutional accounts. Instagram is not the most obvious social network to make sweeping policy statements, however Instagram Stories have become a secondary channel for digital diplomacy, where word leaders meet, greet and tag each other.”
