Summary This contribution discusses the impact of three structural phenomena on the strategic functions of future diplomacy. The first is the shifting global power balance, which has important consequences for the manner in which European ministries of foreign affairs reposition themselves with regard to both big and middle powers. The assertiveness of big, revisionist states implies a return to realpolitik in which hard power takes centre stage. The ascendency of middle powers reinforces the need to build equal partnerships with increasingly influential non-Western countries. The other two game changers are the existential challenges of climate change and the ascent of artificial intelligence. A conflict-sensitive climate approach requires an adjusted diplomatic toolkit. Artificial intelligence has an effect on many different policy dimensions, from international governance to trade promotion. All these developments are relevant to the practice of diplomacy and the skills diplomats need in order to navigate through a changing global environment.
