For example, if there are problems for which it will take a long time to form a global consensus, it may be possible to reach a consensus relatively quickly among specific regions. This is a case where regional cooperation lowers barriers to globalization in countries within the regions concerned.
Furthermore, if there is a common platform for discussion or a framework for solving problems in a region which consists of countries with similar economic conditions and policy orientation, we may be able to reduce the cost of global negotiations in the event of international policy conflicts or shocks. In such a case, regional cooperation may supplement a global cooperative framework.
