General Motors (GM 1.20%) is the largest-selling global automaker in China -- but for several years now, German giant Volkswagen (VWAGY -1.11%) has been close behind. So far, GM has been able to maintain its lead. But in some ways, it's already behind: VW's profits in China (and elsewhere) are much greater than GM's.

GM has been steadily profitable under CEO Dan Akerson, but Akerson isn't satisfied -- he is pushing hard to close the gap with VW. In this video, Fool.com contributor John Rosevear looks at the big push GM is making to boost profits in China -- a push that starts with a revival of GM's Cadillac brand.
