Forget China, look at Canada. Virtually identical certification requirements, virtually identical cars (sans MP/H vs KM/H and F vs C), but high-end Audi like S6 used to cost 100% more than in the US. They enforced this by forbidding US dealerships to sell to Canadians, by voiding the warranty and forcing to go through expensive re-certification. There's nothing to understand. In theory, there's free trade, but "it's not here in particular".
