We know that fitting out and commissioning these kinds of factories takes foreign workers who have the subject matter expertise on how the parent company does it. But we have a history of not providing proper work visas for it and looking the other way.
On the other hand, if you don't let these people in, it's not clear how Hyundai gets a functional battery factory that's built like their other ones.
The old policy of looking the other way was broken. But suddenly "fixing it" with enforcement isn't too smart, either.
