But Chinese cars can sell here at no markup.

Worse! Not only without any markup, but even under fair market value, since they're made with slave labor and subsidies for "developing nations." It's one thing to import cheap plastic appliances, but it's another thing to undermine such a major economic driver like the auto industry. The CCP are ingrained cheaters and don't know how to do business any other way. They cheat their neighbors and they cheat their own people, which is why every Asian and African country hates them.
