Aka how to shoot yourself in the foot and hand over the market to Chinese manufacturer. In Europe, only Renault created a low cost brand (Dacia). Once chinese brands become commonplace everywhere, tradional carmakers will have a hard time taking back market share. In Europe they closed or are closing the last HCOL factories, killing any remaining brand loyalty.
The sad thing is it'll be a slow death. As American / German / Japanese still hold cultural cachet over Chinese/ Vietnamese cars, the companies will delude themselves into going off a cliff till a new gen comes and doesn't care about that cachet and just cares about price
Problem is, we'll probably never let Chinese vehicles in as it is an existential threat to the US auto industry. It's odd because we allow Japanese, Korean, etc. but we have political beef with China as a global power rivaling ours.
