And you are doing exactly that.
China is showing vast stupidity by supporting Mugabe and Bashir. There were plenty of other places that they could have invested time and money and gotten a far better return but like to like and China has an affinity for murderous thugs that will come back to bite them.
Somehow the murderous thugs are always on the other side
"China is showing vast stupidity by supporting Mugabe and Bashir."
You mean like the US did with Saddam, Castro and countless other dictators?
As A. Pole has already stated, the Chinese are very pragmatic and unlike the US, their moves are very calculated with a great deal of thought given to the long-term future.
I wouldn't say the Chinese are being stupid at all. There's obviously something they want and apparently they're getting it.
