Very detailed and insightful post on Quora that I found. https://www.quora.com/Can-the-US-de...Dongye-Qimeng?ch=99&share=2c089cac&srid=Qh1bw Looks like the high end chip supply lines and aircraft is where China has the greatest vulnerabilities. It will take a lot of resources and time for China to recover if these supplies were cut off, as the Huawei and ZTE cases have demonstrated. The COMAC project is extremely vulnerable. It will essentially be dead if it lost Western components, which make up essentially the entire core guts of the plane. The Chinese components are only the shell of the plane. China's smartphones are extremely vulnerable to getting cut off. DJI is as well. China is stronger in other industries however.
