The bilateral relationship between the United States and China is arguably the most important in the world today. The two countries make up approximately 42 percent of the world’s economic output and more than half of global military expenditure (at $801 billion, the US share of that total dwarfs China’s). The Biden administration’s recently released National Security Strategy names China as “the only competitor with both the intent to reshape the international order and, increasingly, the economic, diplomatic, military, and technological power to do it.”
