It could have been brought into China from anywhere. It is a fact, not a conspiracy theory, that there were people from all over the world congregated in that city for a period of weeks shortly before the first cases came to light. I don't think it would be right to blame China or anybody unless it turned out that it was planted/cooked up in a lab. China has its' enemies so who knows, but we've already seen some poor Chinese-British lad beaten up in the streets over here directly because of this association. Not helpful going down that route.
