That 13-17% VAT sounds about right, but compared to the 17-27% EU VAT which has been around since, forever, sounds tame. Doesn't it all depend on the country and its market? Some industries are highly valued and imports would devastate that market so they, like we, protect certain industries in our respective markets. It's done all the time.
As for what Biden did, yes, he did impose a 100% tariff on Chinese government subsidized EVs to stop undercutting our EVs made here. Countries do it all the time but one must look at the underlying reasons for doing so. China made 30 million EVs but could only sell 22 million in country so their government tried to sell out of country, undercutting real world prices for them. You know, dumping. What Biden did was retaliatory.
Biden's tariffs were largely symbolic since they were imposed as he was leaving office. That, and Rump simply banned Chinese EVs once he came into office.
All the best,
