DETROIT -- General Motors Co., taking another step to fine-tune international operations, is creating a sales region for South America. It used to be part of GM International Operations, which encompassed all countries outside of North America and Europe, but now becomes GM's fourth global region.
Jaime Ardila will head GM South America out of Sao Paulo, Brazil, reporting to CEO Ed Whitacre. He leaves his post as president of GM Mercosur, which covers Argentina, Brazil, Paraguay and Uruguay.
GM also is shifting Denise Johnson, now vice president of labor relations, to president of GM Brazil starting July 1. She will report to Ardila. Catherine Clegg will succeed Johnson, vacating her post as GM North America manufacturing manager. GM said it would announce Clegg's successor soon.
