The rise of globalisation and regional trade cooperation led to the creation of various international blocs that offer many economic opportunities to their member states. Some of those organisations feature citizenship or citizenship-like regimes. At the same time, EU citizenship is usually compared with national citizenship statuses. This chapter undertakes to compare Union citizenship with similar regimes found in other regional alliances. Specifically, it compares EU citizenship with similar categories in MERCOSUR, CARICOM, ASEAN, ECOWAS, GCC, and EAC. The analysis shows that Union citizenship is the most advanced example of supranational citizenship, although similar statuses found in some other regional blocs are quite developed.
