Geopolitical tensions between the United States and China have sparked an ongoing dialogue in Washington about the phenomenon of “decoupling”—the use of public policy tools to separate the multifaceted economic ties that connect the two powers. This issue brief provides a historical lens on the efficacy of one specific aspect of this broader decoupling phenomenon: using export controls and related trade policies to prevent a rival from acquiring the equipment and know-how to catch up to the United States in cutting-edge, strategically important technologies.

China’s "Science and Technology Daily," a state-run newspaper, published a revealing series of articles in 2018 on 35 different Chinese technological import dependencies. The articles, accessible here in English for the first time, express concern that strategic Chinese industries are vulnerable to any disruption to their supply of specific U.S., Japanese, and European “chokepoint” technologies. This issue brief summarizes the article series and analyzes the Chinese perspective on these import dependencies and their causes.
