Start date: 4 May 2026

Diplomacy in the 21st century is more proactive, multidirectional, and innovative than ever before.

Our world is increasingly interconnected, as demonstrated by the domestic impact of external issues. New subjects crowd the international agenda. At home and abroad, many actors participate in international affairs. Managing external affairs is more complex, involving focusing on performance and reaching out to publics. This course gives insight into the contemporary practice of diplomacy and deepens understanding of significant issues in diplomacy management. The course is practitioner-oriented, and participants should have some prior knowledge of diplomatic theory and practice. The course was originally developed in a shorter, self-learning format for the Canadian Foreign Service Institute.

21st Century Diplomacy

Text – Shannica Plummer-Antoine

Diplo alumna Shannica Plummer-AntoineWith the advent of globalisation, diplomacy has been transformed both in content and nature. The course provided greater insights into the changes in international affairs that are the result of globalisation, as well as how foreign ministries have had to adapt to these changes. This course has also broadened my knowledge and enhanced my ability to reason.

Text – Elizabeth Bailey

Diplo alumna Elizabeth BaileyThe course offered an opportunity to understand the impact of globalisation in diplomacy and in facilitating the greater use of information and communications technology. It also helped me understand how the public, who wants to have a say in diplomacy, can have better access to information. I particularly liked the area of public diplomacy and the importance of understanding sources, influences, and public contributions in diplomacy, and calls for the consideration of their views in making policies and decisions in diplomacy.

Text – Michael Bulwaka

Diplo alumnus Michael BulwakaThe course has helped me to redefine my role as a diplomat and to appreciate the emerging challenges and responsibilities of diplomacy today, including the role of new actors like NGOs, think tanks, and academics. I have learned to appreciate other stakeholders as partners and not competitors to the Ministry of Foreign Affairs in the conduct of foreign relations.

Who should apply

This course will be of interest to:

  • Practising diplomats, civil servants, and others working in international relations
  • Postgraduate students of diplomacy or international relations wishing to gain deeper insight through interaction with practising diplomats
  • Postgraduate students or practitioners in other fields seeking an entry point into the world of diplomacy
  • Journalists, staff of international and non-governmental organisations, translators, business people, and others who wish to improve their understanding of diplomacy-related topics

Overview

The course consists of 8 modules:

  1. Globalised diplomacy: A survey of the diplomatic process, with a special focus on factors driving change. We consider the environment in which foreign ministries operate; the enlarged, complex foreign-domestic interface; the consequences of the ICT revolution; human rights and the role of civil society; multilateral diplomacy; and human resource management.
  2. Regional diplomacy: This is a high growth area in external affairs, consisting of neighbourhood diplomacy, as well as 'plurilateral diplomacy', where groups build on principles other than geography. We examine the role, potential, and opportunities that these new cluster formats offer, as well as the typology and the innovation incorporated. We also study free trade agreements and the limitations of regional diplomacy.
  3. Foreign ministries: Change and reform: After the Cold War, and the onset of rapid globalisation, most foreign ministries engaged in adaptation and reform. We consider the motivation, the models followed, and the priorities in the content of reforms. We also examine new trends in the training of diplomats. We finally consider the pitfalls in the implementation of reform.
  4. The decision process, crisis and risk management: We examine the generic aspects of decision-making in foreign ministries, the decision categories, their practical application, plus crisis and risk management. In addition, we look at the various actors that furnish inputs into decisions, i.e. the official and the non-state actors, knowledge management, and building institutional memory.
  5. Performance management: In public services, performance management (PerM) is the new mantra; MFAs have no choice but to comply with new public reporting formats, 'output budgets' and the like. We examine the impact along three tracks: measuring the efficiency and effectiveness of the MFA and its subsidiary entities; application in human resource management; and performance reporting to publics. We consider the measurement criteria, the downside of performance management.
  6. The re-invented embassy: Thanks to the revitalisation of bilateral diplomacy, the embassy (and the entire diplomatic process) is in renaissance. We consider the new and the changed tasks of embassies, together with relevant examples, plus the caution that needs to be applied in the 'reworked' embassy-MFA relationship, under evolution in some leading countries.
  7. Diplomacy of small states: A survey of a little-studied, yet current topic. We consider the empirical evidence, the options that small states have developed, and their exemplars. We also look at small state diplomatic behaviour and the group diplomacy practised by small states.
  8. The public and image-building: We analyse image-building activities and the role of the public in foreign affairs. We consider the different models of public diplomacy, including the US experience. We look at methods of news management and the way the country brand is promoted. We consider the thesis that public diplomacy is now practised both abroad and at home, and centres on building and projecting a country’s soft power.
