Under the background of the superpower games, the United States actively promotes the de Sinicization of key minerals and constructs a strategic blockade against China, which may seriously affect China's normal resource rights and interests. Based on the critical mineral related data released by the United States Geological Survey from 2013 to 2022, quantitative research was conducted from three perspectives: import dependence, market dynamics, and supply risk. The changes in the security of the critical mineral supply chain in the United States were elucidated, and the means and characteristics of strengthening the security of the critical mineral supply chain in the United States were analyzed. About 90% of critical minerals in the United States rely on imports, with China as its top supplier. The market dynamics of about 70% of critical minerals fluctuate violently, and market instability may amplify the import risk of critical minerals in the United States; About 32% of critical mineral supply risks are high or keep rising, and the production capacity of critical minerals further shifts to some thirdworld countries in Asia, Africa and South America, and the escalation of geopolitical crises may exacerbate mineral supply risks. Based on the analysis of the security situation of the key mineral supply chain in the United States and its security measures to strengthen supply chain, suggestions have been put forward, including systematic planning to respond to the strategic game of key minerals, enhance the influence on the international mineral resource market, deepen overseas development cooperation, and strengthen risk prevention and control.
