Joseph Nye, who famously coined the phrase “soft power”, defined it as “the ability to attract people to our side without coercion”. In his book Soft Power, he suggested three main sources for a country’s soft power: “its culture, its political values, and its foreign policies”. In contemporary international relations the primacy of communicating a favorable image of a country, involving both state and non-state actors and networks, is mostly important (Joseph S. NYE 2005). Mr. Alan K. Herrikson in his discussion papers in Diplomacy referred to various definitions of Public Diplomacy. A definition offered in March 1966 by Dean Gullion, public diplomacy is the means by which governments, private groups and individuals influence the attitudes and opinions of other peoples and governments in such a way as to exercise an influence on their foreign policy decisions. According to Lord Carter of Coles, Public Diplomacy emphasize the need for two-way or interactive communication. The Report of The Public Diplomacy Council, based at the School of Media and Public Affairs of George Washington University, Washington, DC term ‘Public diplomacy seeks to promote the national interest and national security of a country through understanding, informing and influencing foreign publics and broadening dialogue between citizens and institutions of the two countries and their counterparts. Public diplomacy is practiced through tools including holding of lectures, seminars, academic programs, Journalists exchange programs, scholarships to media persons of host country, establishment of cultural centers and libraries, book translation programs, Research grants, language study, co-opting legislators, community leaders, decision-makers in ministries and other organizations, and key religious and political leaders of the host country. One essential element of soft power is cultural diplomacy. Cultural diplomacy is a set of activities undertaken by a country of the origin directly or through its diplomatic missions to promote of foreign policy objectives by introducing its cultural assets in the host country. In practice, cultural diplomacy includes promoting national culture and cultural identity and values and national language in the host state, negotiating international treaties on cultural cooperation, and supporting and keeping up contacts with expatriate communities in the host state. It also covers education, science and technology, sports, arts and literature, archives and heritage, etc. However, the structure, as well as the overall intensity of the cultural-diplomatic activities may vary depending on the state and its foreign policy priorities and ambitions (Pajtinka 2014). This presentation discusses various aspects of Public Diplomacy, with the help of case studies of India, China and Pakistan.
