There are reasons you might buy a vehicle that won't operate on public roads and therefore doesn't need tags, it makes it more expensive for those people (though, amusingly, still less expensive than just about every other EV still)

I saw a Zeekr 001 a couple months ago, probably the only one in the country. Not sure how they managed to get around the super strict import laws but where there's a will (and a shitload of 富二代 cash), there's a way.
