Abstract
This chapter has three core purposes. First – and briefly – we ask why scholars should study regions, regionalism and regional integration comparatively and also set out how we understand the key terms here, that is regions and regional integration. Second, we ask how, once the matters of why and what to compare have been addressed successfully, scholars can actually go about comparative study of regions in the global polity. Finally, we set out how comparative regional integration studies can contribute to Europe-Asia investigations.
