Exactly, they are going to buy and bribe their way in just as they have done all over africa.The Chinese WON'T be going in with their military, they are not as stupid as our politicians.
All China wants is the raw materials and influence in the area.
It doesn't matter how stupid / brutal / primitive your "government" is, you HAVE to have money to pay your goons/police/military/enforcers or they aren't going to do the work for long. In addition most of those "leaders" tend to quietly have a taste for the finer things in life and also supporting their large harems/families/relatives etc. That takes money, specifically money the western infidels/capitalist pigs/fascists/oppressors etc. will accept in return for the stuff you want.
The Chinese will let the Taliban take care of all the "security" to ensure the Chinese run mines produce and ship out the raw materials to China.
Chinese will then provide the needed cash and goods to the Taliban as well as perhaps purchase any spare left over gear they would like to look at (that they don't already have the full plans for).
Anything happens, the Chinese quietly and quickly pull out all their folks, wait till the Taliban run out of money and then resume the arrangement, after deducting an appropriate amount from the next couple payments for "inconvenience".
Unlike our stupid greedy short sighted politicians and our even more short sighted, goldfish like greedy public, the Chinese Communists are steadily working on their 100 year plan for global domination and doing very well at it so far. They don't mind if it takes them another generation or two before they are the new most economically and politically powerful country. The USA has actually been helping quite a bit, first by of course funding them, and then by pissing off pretty much everybody around the world so the Chinese can come in with tons of money and play "nice" and just clean up everything they want.
