I'll also add that earlier this year, the US put a number of Chinese consumer technology companies, including DJI, on a public blacklist that designates them as "Chinese military companies". This is a clear use of the United States' diplomatic power to hurt and discredit Chinese tech businesses. Whether the US should be doing that is another issue. At the end of the day these sorts events are a common biproduct of large power politics, but the point is that China's actions are not unwarranted.
