Global Order and the New Regionalism (Stewart M. Patrick, Miles Kahler, CFR)

Regional institutions and initiatives have proliferated in the twenty-first century. This latest wave of regional innovation raises, in new guise, a long-standing conundrum for global order and U.S. foreign policy: When is regional organization a useful, even essential, complement to the ends of global governance—financial stability, an open trading system, sustainable development, robust protection of human rights, or the end of civil wars—and when does it threaten or undermine the achievement of those goals? The new regionalism presents the prospect for new benefits for global order as well as new risks. How those challenges and risks are addressed, by the United States and by other member states, will determine whether a fragmented global order or more effective global and regional governance emerge over the next decade.
