My thesis was as follows: Chinese companies looking to buy American companies are usually looking for a valuable technology or commodity or, to amuchlesserextent, a strong brand name.
The opposite will likely be true for the coal industry, although to amuchlesserextent, since decreasing domestic coal use under Obama has been partially made up by increasing coal exports.
It was the last vestige, along with (to amuchlesserextent), Titanic and The Sixth Sense, of the idea that a hit film could play in theaters for months and months on end.
So my bet is that the main outcome of the current kerfuffle will be to hand a stick to Labour (and to alesserextent the Lib Dems) to beat the Conservatives with, and make it much harder for them to legislate in a way Labour doesn't like.
