China always has the following nuclear options in response to US getting too uppity.
Ban Apple (Probably threatening to use this card right now)
Ban US car compani
Use all reserves and then US treasuries
Banning private US companies in retaliations against US government is self defeating.This would be going down to the same level of the US government. US companies operating with or in China are Chinese bonus and allies, they are going against the wishes of the Whitehouse. The much better way to deal with US/West bans and sanctions is to innovate and grow China own domestic market and its international trades from Arctic to Antarctica. Being a very much more attractive, innovative, efficient and biggest economy in the world, the center of gravity will be in China, Beijing will then be calling the shots. Western economies will become secondary. This is feasible but requires time and long term planning.
By the way, no need to ban exports such as rare earth. Regulations will do. For every ton extracted/exported, the government can impose a levy for rehabilitation of the environment or scale down the mining for future reserve. Just control the quantity available but do it legally. Banning export is a bad solution with complications. Look at the big picture, don't be blind by rage. The US and allies know what's likely to be coming. They are not telling you about their nightmares, just wanting to stop the China dream. They are also thinking long term you know, but are hamstrung somewhat by their short term governing cycles because they are not willing to take on hard and unpopular decisions for the benefits of future governments. They have re-elections to worry about. Come election time, they will make very generous decisions just to get reelected.
