The global economic edifice built after World War II is a source of unprecedented prosperity. It cannot function without open and predictable international trade, and the peaceful international relations that are its foundation. The rules that enable trade are under attack. Social divisions and great power rivalry have eroded the political support for open trade. The consequence is fragmentation of world trade, its separation into blocks that advance domestic producers or favored nations nearby.
