The means and modes of communication in diplomacy have evolved at a faster rate since the turn of the century than during the entire twentieth century. Today, diplomats and their foreign ministries are compelled to communicate more with more audiences at home and abroad across more media platforms than ever before. Arguably, at the heart of this reboot of public communication in diplomacy, is a reconsideration of the value of public diplomacy within diplomatic practice. This has led to questions about whether the exponential growth in access to information online (via smart telephones, social media, websites, virtual worlds) and the increased activities of sub-national bodies (cities, provinces/states, regions) and non-state actors in the international arena are forcing liberal democracies to engage in a foreign policymaking process that is more open and democratic. The chapter first examines public diplomacy as a field of study, a concept, and as type of statecraft used by major players in the international system. It then analyses the prospect for a more democratic foreign policy resulting from the bottom-up public diplomacy pursued by a growing number of liberal democracies. Countries such as Canada face a world in which soft power must coexist with a resurgence of hard power. This world is characterized by a diffusion of power resulting from the growth of international knowledge networks and movements whose civic goals of finding solutions to transnational challenges are enabled by communication technology. It is also characterized by the axis of two major authoritarian powers—China and Russia—with a highly centralized top-down approach to public diplomacy. This is diplomacy geared for political warfare with the West through the use of broadcasting and online platforms to seize control of the global narrative, to delegitimize liberal democratic values, and to project the superiority of their systems of governance for ensuring social order. The final part of the chapter uses the case of Canadian public diplomacy to explore whether digital diplomacy—the state’s leveraging of emerging information and communication technologies to advance the national interest-can contribute significantly to a more democratic foreign policy. Or, whether networked communication platforms designed for interactivity, exchange and greater institutional transparency have been re-purposed by liberal democracies as additional one-way public information channels to serve the strategic communication needs of their raison d’états in an emerging multipolar world.
