The Shanghai Cooperation Organization
There is a clear trend in the 21st century for regional organizations to multiply, to become more multifunctional and to devote themselves in whole or part to security goals. Old-style alliances with a defined opponent are now rare, and most groups address themselves to the reduction of conflict (internally or externally) and to transnational challenges such as terrorism. It is no coincidence that regions where these structures are absent or weak are also those with the greatest remaining problems of interstate tension or internal violence.
