The conventional wisdom has held that China's economic power is very close to America's and that Washington cannot undertake a broad economic cutoff of China without hurting itself as much, or more. Command of Commerce shows that the conventional wisdom is wrong--America's economic power has been vastly underestimated and China's overestimated. Across multiple scenarios, the book shows that China's economic losses from a broad cutoff would be far greater than America's. A powerful analysis of the true scope of US and Chinese economic power, this will reshape our understanding of the most important geopolitical rivalry in the world.
