For the same reason that only China can produce t-shirts, or a quality sedan EV with a 5-star EU crash test rating and 350 miles of range for $15,000.

China isn't subsidizing BYD or some t-shirt sweatshop anymore than the US is subsidizing Ford.

		Does that mean to say "the Chinese government regularly subsidizes BYD"? Because the US regularly subsidize Ford, and I don't think you'll find any one that disagrees with that.
