VinFast Auto is a Vietnamese company that makes electric vehicles—cars powered by rechargeable batteries instead of gasoline. Its founder, Pham Nhat Vuong, one of Vietnam's richest people, has stepped down as CEO. His son, Pham Nhat Quan Anh, is now taking the top job. This leadership change is happening as VinFast is trying to grow around the world, entering new markets beyond Vietnam.
