How would you want to pressure China? China is exporting nuclear power plants to Britain and electric cars to the EU. They are an advanced country that does not need western technologies. Unless you do a naval blockade, China doesn’t need us but we need China.
This sounds impressive without anything that is existential for China. All commodities can be replaced if China pays a small premium for nonwestern sources while the rest of the world buys from western sources.
Airplane parts are inconvenient but China is starting to build their own aircrafts. If sanctions start, they will be able to create knockoffs for all necessary spare parts. But they also have a highspeed rail network, so they won’t be worried too much.
At this point in development, pressuring China will only accellerate the full independence of China. It would be Huawei on a national scale.
The dangerous part is that many former colonies won’t side with their former masters if they get the opportunity to break free.
