Book excerpt: This book examines Africa’s internal and external relations by focusing on three core concepts: orders, diplomacy and borderlands. The contributors examine traditional and non-traditional diplomatic actors, and domestic, regional, continental, and global orders. They argue that African diplomats profoundly shape these orders by situating themselves within in-between-spaces of geographical and functional orders. It is in these borderlands that agency, despite all kinds of constraints, flourishes. Chapters in the book compare domestic orders to regional ones, and then continental African orders to global ones. They deal with a range of functional orders, including development, international trade, human rights, migration, nuclear arms control, peacekeeping, public administration, and territorial change. By focusing on these topics, the volume contributes to a better understanding of African international relations, sharpens analyses of ordering processes in world politics, and adds to our comprehension of how diplomacy shapes orders and vice versa. The studies collected here show a much more nuanced picture of African agency in African and international affairs and suggest that African diplomacy is far more extensive than is often assumed. This book will be of much interest to students of diplomacy studies, African politics and International Relations.
