Public diplomacy refers to the practice by which a state communicates directly with citizens of other countries to shape perceptions, build relationships, and create an environment more receptive to its foreign policy. The term is generally credited to Edmund Gullion, a former U.S. Foreign Service officer who used it in 1965 when founding the Edward R. Murrow Center of Public Diplomacy at the Fletcher School, Tufts University. It was coined in part to distinguish legitimate transparent communication from "propaganda," a word freighted by the Second World War and early Cold War.

Typical instruments include:

International broadcasting (e.g., Voice of America, BBC World Service, Deutsche Welle, France 24, RT, CGTN).
Educational and cultural exchanges such as the Fulbright Program, the British Council, the Goethe-Institut, the Confucius Institutes, and the Japan Foundation.
Embassy outreach, social media engagement, press briefings for foreign journalists, and visitor programs.
Cultural diplomacy through film, sport, language instruction, and the arts.

Scholars often link public diplomacy to Joseph Nye's concept of soft power—the ability to obtain preferred outcomes through attraction rather than coercion or payment—developed in his 1990 book Bound to Lead and elaborated in Soft Power (2004). Nicholas Cull's typology distinguishes five components: listening, advocacy, cultural diplomacy, exchange diplomacy, and international broadcasting.

A distinction is often drawn between traditional public diplomacy, which is largely one-way messaging, and "new" public diplomacy, which emphasizes dialogue, network-building, and engagement with non-state actors, sometimes via digital platforms ("digital diplomacy" or "Twiplomacy"). Critics note the line between public diplomacy and propaganda or disinformation can blur, particularly when state broadcasters operate covertly or amplify divisive content. Institutionally, the United States consolidated public diplomacy under the U.S. Information Agency (USIA) from 1953 until its functions were folded into the State Department in 1999.

Frequently asked questions

How is public diplomacy different from propaganda?

Public diplomacy is generally transparent, attributed to a government, and seeks long-term relationship-building, whereas propaganda typically conceals its source or intent and aims to manipulate. In practice the boundary can be contested, especially with state-funded broadcasters.

Who coined the term 'public diplomacy'?

It is widely attributed to Edmund Gullion, a former U.S. diplomat, in 1965 at the Fletcher School of Law and Diplomacy at Tufts University.

Is public diplomacy the same as soft power?

No. Soft power, as defined by Joseph Nye, is a resource or form of influence based on attraction. Public diplomacy is one of the tools governments use to cultivate and project that soft power.
