> Chinese car joint ventures has been ran for a decade but still Chinese can't design a decent car.

such joint ventures have been there for 3 decades, vw is the first western company that started such joint ventures back in the mid of 1980s. they are not stupid, they won't tech you the know how whatsoever. the best example here is the fact that Volkswagen Santana was the only model built and sold by that joint venture between vw and SAIC back in the 80s, 90s and early 2000s.
