But if they did that, is it necessarily bad? They should still keep pressure on the Dutch.
But if Nexperia China can bypass the European fabs entirely and source all front-end manufacturing from Shanghai fab, get all customers to deal directly with China and is able to sustain volumes beyond the domestic needs, I think it's better to resume exports to retain as many customers as possible.
Even if/when Dutch agrees to give back control of European fabs, it is probably not a good idea for WingTech to hold on to those. UK politicians are already talking about forcing the sale of Manchester fab, which they already did with Newport fab.
