Public diplomacy to promote Global Public Goods (GPG): Conceptual expansion, ethical grounds, and rhetoric

Traditional conceptualizations of public diplomacy stress three dimensions, namely image cultivation, advocacy of national interests, and promotion of mutual understanding. This research expands the scope of public diplomacy by adding an additional dimension, namely promotion of Global Public Goods (GPG). The research argues that creating and preserving GPG should be one of the functions of public diplomacy in an era when global warming and globalization of health become realities that dictate the entire humankind to meet the challenge in collective action. The research also explored the ethical grounds and rhetoric of the new dimension of public diplomacy.
