Predictions of the 21^st century as an Asian century led by burgeoning Asian economic, political, and military powers appear on course with the impressive and growing wealth and power of such rising Asian states as China and India, backed by the already well developed economies of Japan, South Korea, and others that used to be called newly industrialized countries. There also is a great deal of discussion regarding Asian nations asserting leadership in managing regional affairs through regional and sub-regional groups and other means, and thereby challenging and marginalizing the leading roles played by the United States and other world powers and institutions in Asian and world affairs. But the accomplishments are much more limited.
