Kia Motors Corp., South Korea\'s second-largest automaker, said Tuesday it will look to expand its presence in China\'s premium car market in a bid to increase its share of the world\'s largest car market. Jung Chang-ho, head of Kia Motors\' China operation, said the carmaker plans to put more focus on meeting demand from China\'s growing middle class, seeking to differentiate itself from Chinese rivals with its premium brand image and advanced technologies.
