In short, America’s restrictionists—zero-sum thinkers who urgently want to accelerate technological decoupling—have won the strategy debate inside the Biden administration. More cautious voices—technocrats and centrists who advocate incremental curbs on select aspects of China’s tech ties—have lost. This shift portends even harsher U.S. measures to come, not only in advanced computing but also in other sectors (like biotech, manufacturing, and finance) deemed strategic. The pace and details are uncertain, but the strategic objective and political commitment are now clearer than ever. China’s technological rise will be slowed at any price.
