Ongoing shifts in geopolitical power from West to East make the Asia-Pacific region more important to the United States today than ever before. The region is already an engine of the global economy, and major Asian countries are becoming global economic and political actors. Yet, as Asia’s importance has grown over the last decade, Washington has often been focused elsewhere. The Obama administration needs a more active approach to the Asia-Pacific region that recognizes the new geopolitical realities and positions the United States to deal effectively with the challenges and opportunities that lie ahead. Such a strategy must build upon America’s long-standing positive engagement in Asia and articulate a vision that can  advance U.S. interests and attract support from countries in the region.
