The United States and China are engaged in a broad-gauged and global competition for power. While this competition ranges across the entire world, it is centered in Asia. In this book, David Shambaugh focuses on the critical sub-region of Southeast Asia. The United States and China constantly vie for position and influence across this enormously significant area - and the outcome of this contest will do much to determine whether Asia leaves the American orbit after seven decades and falls into a new Chinese sphere of influence. Just as importantly, to the extent that there is a global "power transition" occurring from the US to China, the fate of Southeast Asia will be a good indicator.

Presently, both powers bring important assets to bear in their competition. The United States continues to possess a depth and breadth of security ties, soft power, and direct investment across the region that empirically outweigh China's. For its part, China has more diplomatic influence, much greater trade, and geographic proximity.

In assessing the likelihood of a regional power transition, Shambaugh examines how ASEAN (the Association of Southeast Asian Nations) and its member states maneuver and the degree to which they align with one or the other power.
