Yes, same thing really. There will be issues of some kind or another with Chinese built cars for some number of years. I don't think they'll be at the same state as the Japanese for at least 5 years, but more likely 10 to 20.
To compete, the Chinese will need to sell their cars for considerably less than the Japanese & Koreans. I don't think they'll be cheap enough to tempt me for at least 5 years, maybe never. But I recall the die-hards of the 60s and 70s who vowed and declared they would never buy Japanese, many as much for ideological reasons post WW2 as for quality reasons... I wonder where they are now? Probably most of them are dead.
A quick Google
Germany's major car brands have been producing cars in China for decades.
Yes they operate under supervision I assume, but if China wants to make quality cars, they can. Labour is cheaper, so theoretically they can make a more cost efficient car
