Since the 20th century, when modern democracies gained more strength, governments carry out their internal and foreign affairs policies with the approval of society. For that reason, all organizations that want to influence the governments try to gain a reputation in the eyes of the public. Similarly, states also attempt to build a reputation and trust in the public opinion of a target country or within particular target communities through public diplomacy activities. It is seen that remarkable public diplomacy studies and works have been carried out for more than half a century and the field has advanced. However, the public diplomacy literature is mainly USA-dominated due to its pioneering role in the emergence of the concept and its institutionalization. Public diplomacy perceptions and practices in other countries also develop under the influence of this experience. With this effect, each country determines its practice areas and actors for public diplomacy within the consideration of its power, sphere of influence, opportunities, and risks. The purpose of this book is to examine the public diplomacy activities of countries with different power levels in different geographies.
