As Donald Trump prepares to jet into Asia this weekend, government officials and diplomats around the region are focused on one critical question: Are we witnessing the decline of the mighty United States hegemony in Asia?

David Shear, former US assistant secretary of defence for Asian and Pacific security affairs in the Obama administration, is among those sounding the alarm, raising the possibility of a "peaceful erosion" of American power in Asia that "ends with Beijing's establishment of a Sino-centric economic and security order in Asia". Shear writes about his concerns in a special report publised by the US Studies Centre.
