Recently, the US army is withdrawing from Afghanistan. Some Western countries, such as the US, the UK and Germany, played an important role in Afghanistan for several decades. But China does not seem very interested in Afghan affairs. It seems that the Chinese never took action. But of course China has great ambition. It is almost impossible for them to do nothing in such an important area.

So, my question is: What did the Chinese do when there were still a lot of Americans in Afghanistan? Also, what are they doing now?

Thanks!
