When we think of processes such as diplomacy we usually think of receptions, dinners and heavily coded conversations between state representatives. Yet there is a way to think about the complexity of this relationship in terms of how it operates through a range of material and immaterial practices from the rise of paper records in the British Empire to the procedures for standardisation for equipment between NATO countries. here I talk with Jason Dittmer, Professor of Political Geography at University College London about his book Diplomatic Material:Affect, Assemblage, and Foreign Policy.https://www.ucl.ac.uk/geography/jason-dittmer
