You wouldn't know it from the cars on the streets in Seoul, but General Motors (NYSE:GM) is South Korea's third-largest automaker. GM makes cars and SUVs in Korea for export to markets around the world -- a strategy that has helped keep costs on some smaller models competitive.

But costs are rising, thanks to a combative local union -- and GM is hinting that it might take its production elsewhere. In this video, contributor John Rosevear looks at the war of words between GM and the local Korean union -- and at why it might make sense for GM to move its operations elsewhere.
