The USA employs sport fo[r] the sake of public diplomacy. W[i]thin this sports diplomacy basketball coaches and players (and coaches and players of other sports as well) are sent abroad in order to share their knowledge during camps, clinics etc. This is conducted through programs like NBA's Basketball Without Borders, SportsUnited sports envoys etc. Can anyone recommend any publications on the issue?
