Cultural diplomacy is a type of public diplomacy and soft power that includes the "exchange of ideas, information, art, language and other aspects of culture among nations and their peoples in order to foster mutual understanding". The purpose of cultural diplomacy is for the people of a foreign nation to develop an understanding of the nation's ideals and institutions in an effort to build broad support for economic and political objectives. In essence "cultural diplomacy reveals the soul of a nation", which in turn creates influence. Public diplomacy has played an important role in advancing national security objectives.
