International exchange programmes have been previously conceptualised based on the ‘opinion leader model’. It expects participants to form positive attitudes towards the host country, and to become influential back home. However, the micro-processes through which this goal can be achieved remain undertheorised. Drawing from Interaction Ritual Theory, this article argues that international exchanges consist of a chain of rituals. They strategically immerse targeted individuals into personal experiences with a shared focus on the host country, transforming the latter into a symbol charged with emotional energy and (strategically devisable) cognitive content. The symbol (now affectively and cognitively laden) is then recurrently invoked to re-circulate through the networks of the participants. A case study of a programme in which the symbol ‘Poland’ became systematically charged with the content of ‘multiculturality’ illustrates this proposition. Practical and theoretical implications (e.g. for the literature on socialisation, norm-diffusion, and face-to-face diplomacy) in international relations are discussed.
