China's capacity to supply both US and European car markets

A poster says China can produce 50–55 million cars, while its domestic car market fell from about 25 million to 20 million in 2026. They argue China could export 2–3 million cars to the US alongside 1.5 million to Europe. They say US tariffs block GM and Ford from selling cars from their Chinese joint ventures back to the US, but reject the idea that China couldn't serve both markets.
