Due to a large number of manufacturing operations in China, most large US chip companies are vulnerable to such threats. In 2019, 28% of Intel's total revenue came from Chinese customers, Nvidia accounted for 25%, Qualcomm (Qualcomm) accounted for 67%. US chip suppliers have already lost billions of dollars in the first round of sanctions. If China counters the new round of sanctions, it may lose tens of billions of dollars.
