A fundamental axiom of economics is that when two individuals or countries trade, both are better off. In the decades after World War II, the U.S. was the world’s largest exporter and economy and as it grew, it imported more, helping its partners. As they grew, they bought more of what the U.S. made. Expanding trade helped everyone specialize, leading to more competition, innovation and choice, and lower costs.

China is now the world’s second-largest economy and its largest exporter, but its philosophy is quite different. It has never believed in balanced trade nor comparative advantage. Even as it imported critical technology from the West, its long-term goal was always self-sufficiency. In 2020, Chinese leader Xi Jinping codified this approach as “dual circulation.” This would, he said, “tighten the international industrial chain’s dependence” on China while ensuring China’s production was “independent” and “self-sustaining.”

And as China expands into high-end manufacturing such as aircraft and semiconductors, Xi has decreed it must not relinquish low-end production such as toys and clothes. Beijing has discouraged Chinese companies that invest abroad from transferring key know-how, such as in the production of iPhones and batteries. Xi has rejected fiscal reforms that would tilt its economy away from investment, exports and saving and toward household consumption and imports.
