I'm not sure "handle" necessarily means "prevent" or "halt". It seems reasonable, upon observing a growing trend in Chinese ownership of one's domestic economy, to want to formulate a plan to monitor and understand that trend, and to be ready to regulate or mitigate it if it proves to be pernicious to to have unwanted consequences. And, while I cannot say that I know what is in the minds of those officials in Europe, i suppose the main difference (as compared to US or middle eastern companies) might be the suddenness/newness of the trend and the rate at which they are buying up the economy. Of course, this could be the "Summer of the Shark", as discussed in an HN thread last week.
