SHANGHAI, Feb 6 (Reuters) - General Motors Co and its Chinese joint ventures sold 339,781 vehicles in China in January, down 2.4 percent from a year earlier, the U.S. automaker said on Friday.
That follows a 31.9 percent year-on-year rise in December and a 5.3 percent rise in November. In 2014, GM's China sales rose 12 percent.
GM has said it plans to invest $12 billion in China between 2014 and 2017 and build more plants to ramp up its manufacturing capacity.
