The Quai d'Orsay has taken the initiative in flogging French exports, according to Le Monde, and has thus irritated the upstream Quai de Bercy. Hence the War of the Two Quais. But why not a Bridge over the River Quai instead (forgive me!)? Would it be too much to expect the two ministries to work together in the national interest?
The devil, I suppose, is in the details, and this is an area about which I don't have much detailed knowledge. But if I were an American businessman looking to do business in France, I might not even know the name of the Quai Bercy, but I would be able to find the phone number of the nearest consulate in my phone book. Hence it seems to me perfectly reasonable for Fabius to seek to gin up his ministry's capabilities on this front.
