 In symmetric (con)federations the member units have the same bundles of powers, while in asymmetric (con)federations such as Russia, Canada, the European Union, Spain, or India the bundles may be different among member units; some member units may for instance have special rights regarding language or culture. Some asymmetric arrangements involve one smaller state and a larger, where the smaller partakes in governing the larger while retaining sovereignty on some issues (Elazar 1987, Watts 1998).
