i never done business in France
Having done business in both I suggest that each country and other jurisdiction has positive and negative features. Those who know the details are always better off than those who do not. It is easy to throw obsessions about each locations. We really should stop with the political histrionics, that is OFF TOPIC and ought not be here.
Selecting the next location of a GigaFactory does have plenty of variables to consider:
Liaoning (probably Dalian) has large advantages in engineer and technical resources, The Intel Fab, Chery, BYD (electric busses), Nissan (Dongfeng) couple with almost all the major Japanese and Korean suppliers. Logistically that has excellent port facilities.
Slovakia helps coming up, but several other EU members that are less expensive and bureaucratic than Northern European certainly reasonable.
Then there are raw material source locations such as Indonesia,Brazil or a half dozen others. Some of those
will appear, if only to stabilize longer term materials supplies.
Then there is Mexico, which has tariff advantages for export to the former NAFTA as well as Mercosur. Many manufacturers find that compelling.
So we can speculate.I cannot help but believe that the next one will be oriented to optimize tariffs and other impediments.
The only things that seem obvious is that it will probably not be California, Texas, Germany, France or the UK, most likely not in Northern Europe.
