My point is that those incidents were not the fault of the Chinese workers and companies. I have not heard of any industrial strife anywhere in the world concerning any foreign company that required the evacuation of foreign personnel en masse. Of course, I am talking about modern times, not colonial. Even the riot that ensued from the Bhopal disaster did not trigger the mass evacuation of Americans by chartered flights.
If the fault was intentionally cause by Chinese workers and companies you would be right. But that was never my main contention in any of my posts, the same goes with industrial strife.
My post if you will recall uses the word "afoul" (in a very neutral sense) which means that Chinese entities would even face backlash by the simple fact of being there. Again refer to the evacuation of Libya and Yemen, was the incident the fault of Chinese workers or companies ? No, but did it required the evacuation of Chinese entities in the region ? The answer is an resounding "yes" on all accounts.
The Bhopal incident is a poor comparison due to several reasons
1) US investments and expats in India never reached a level that draws great amounts of attention, while China's certainly is in the countries that are on the receiving end.
2) The Bhopal incident was a one off case that involves just 1 country, now compare it with China's investments in Sri Lanka's port, the development of Gwadar, the take over of Kenya's port and similar investments in Malaysia that follows a similar trend. These are good reasons why some people would be leery.
