From Myanmar to South Korea, Indonesia to China, the once strong states of Asia are fading. Previously capable of driving rapid major policy reform, almost every country in the region now faces greater constraint on the executive branch of government. One driver is institutional change, such as the increased power of legislatures and courts. Another is shifts in political preferences away from an emphasis on national security and economic growth. Others include the transformation of markets for information and heightened global engagement. The pace of change varies, but the direction is clear.
