A Japanese company, AESC, stopped building a big factory in South Carolina. They said they are not sure about the rules. The factory was for BMW electric cars. The governor thinks it is because of new rules for electric cars. But AESC will still hire 1,600 people and spend money. Another company, Scout Motors, will build electric SUVs there. People are worried that new rules could make it hard for foreign companies like BMW to work in South Carolina.
