Xiana Mendéz, Spain’s trade minister, recently told the FT that Madrid would favour the move. Spain is the second-largest carmaker in Europe by volume, producing 16 electrified models. “We would be sympathetic. We have a value chain between the EU and UK. It is in the mutual interest for the right rules of origin to be in place. If we import batteries from Asia that has to be taken into account
As Spain pointerd out they have a value interest between the EU and UK. Also as the article states if the UK is in favour but the EU not the other side would seek to want something in return-that works both ways. It also in the UK and EU interests to buy batteries from Asia, as neither the UK or EU have enough facilities to build there own yet, so the EU would be a fool, otherwise they will not have any batteries for EV’s if they aren’t imported.
Its an old story where by a EU or UK built car would gradually rely more and more on it’ own building resource. Howevery battery materials would still have to be imported regardless.
