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.
China doesn't need exports for their economy. The Chinese citizens can perfectly consume everything on their own. Countries only have to export to finance imports. In China's case, it would be enough to export to the countries that deliver the raw materials.
China will be friends with all those countries because Colonialism will make those countries prefer China over Europe. China is even pushing the Monroe Doctrine and becoming friends with countries in South America.
It's not China that needs friends but Europe. For some reason, we are ignoring Bismark again and are on our way to isolate us in preparation for the next global war. This time not only Germany, but all of Europe.
