The sovereign power of the nation-state has been steadily eroding for decades under the pressure of multilateral organizations such as the United Nations and multiregional organizations such as the European Union. The increasing prominence of non-governmental organizations such as Greenpeace and Human Rights Watch in times of crisis has also contributed, since the problems such groups address often extend beyond national borders and are thus difficult for national governments to manage alone. Multiregionalism and Multilateralism investigates these forces as they factor into political and economic relations between Asia and Europe.
