Geely, China's most successful carmaker, sold 20 percent more cars in 2018, but this was sharply lower than a 63 percent growth in 2017. It is forecasting flat sales this year. Japan's Toyota Motor, however, bucked the trend, with a 14.3 percent rise in sales in China, versus 6 percent growth in 2017, helped by better demand for its luxury brand Lexus and improved marketing efforts.
