The ban primarily impacts Polestar's operations in the US, where it had been selling vehicles like the Polestar 3, manufactured in South Carolina, and the Polestar 4, built in South Korea. US consumers seeking Polestar vehicles will face limited availability, and the company may lose a significant market share in the region. The decision underscores broader tensions between the US and China, particularly in the automotive and technology sectors, and could set a precedent for other manufacturers with similar ties.
