This may be the minimum.

I would think that building planes, as expensive as they are, would mean that you would want to sell them to everyone. In order to sell in a country, you probably have to commit to building (or assembling) some parts of it in that country. Breaking it up the way they did probably is as efficient as they can make it now. I guess we'll see in some years how that turns out financially for them.
