Different criteria. I have had first hand experience with the Chinese stealing/copying tech in companies we have invested in, prompting me to not want to do any more business with them. I have had several investments along side investors from SA and Qatar and they have all been difficult, but they did not steal the tech. Heck, one of those investments we made with SA investors actually had the tech copied in China for use in China. My stance is not a "general" position, but one based on first-hand experience. So, where I can make an alternate decision, I will.
I haven't sworn off all-things Chinese, but it does factor into my decision process when given a choice.
