General Motors (NYSE:GM) has long been a sales leader in China. While Volkswagen (NASDAQOTH:VWAGY) has invested big in an effort to overtake its archrival, GM's vast Chinese operations continue to post solid sales gains month after month, and good profits quarter after quarter.

October was no exception. Strong sales by the Buick and Cadillac brands, and a fine showing for the Chevy Cruze, drove another strong monthly gain for GM in the world's largest auto market. As Motley Fool contributor John Rosevear explains in this video, GM's steady work in China has gained it a wide following among increasingly discerning Chinese consumers -- one that continues to pay off for GM shareholders.
