Given what we already see playing out in Europe and America's existing history of trade policy with China, I suspect politics/trade policy will likely be very unkind to allowing imports of cheap chinese cars to the US any time soon.
European and Japanese manufacturers are already getting that nasty surprise in European markets competing with Chinese EVs like the MG4 etc.
MG is a Chinese native brand in my eyes and a lot of European consumers - it's widely known it's a Chinese product even if consumers don't know of SAIC. This isn't like they bought 51% of some European car company and kept the same management, workers and factories; none of the cars are made in Europe, they are largely made in China and sold around the world with the logo of a failed UK car manufacturer SAIC acquired decades ago etc.
Certainly very few customers think they are buying a British product! It also hasn't prevented the MG4 from picking up a lot of critical acclaim/car of the year awards in Europe too, and virtually every review of the car mentions its Chinese origin, usually in the context of it offering more EV for less money in several regards than a European ID3 etc.
Sure, then what do you think explains such a high disparity between MG's and local Chinese brand's EV sales in EU? The best selling Chinese EV brand, BYD, has 0.6% of regional market share.
