Developed and developing countries alike would benefit from greater economic-policy coordination. While regional groups may obtain some short-run benefits by pursuing narrower interests outside of multilateral channels, neither emerging nor advanced economies can fulfill their long-run potential in an environment characterized by isolationism and a zero-sum mentality in areas like trade and exchange-rate policy.
发达和发展中国家能从进一步经济政策协作中获益。地区集团或许可以从追求多边渠道外的狭隘利益中获得短期好处，但不论是新兴还是发达经济体，都无法在孤立主义以及贸易和汇率政策等领域的零和思想环境下实现长期潜力。
