The South African arm of General Motors Corp. (GM) said it won't be affected by its parent's bankruptcy filing Monday.

GM South Africa isn't part of the filing in the U.S. and creditors of the parent would have no claim on the South African unit as it hasn't guaranteed any U.S. obligations or had any of its assets used as security for GM's obligations, the company said in an emailed statement.

"We continue to generate our own cash and are responsible for our own viability. We are a self-sustaining operation and as such will continue to operate as normal," said Steve Koch, president and managing director of GM African Operations

GM has operated in South Africa since 1926, selling Chevrolet, Isuzu, Opel, Hummer, Saab and Cadillac brands.

Koch said the unit's plans to invest in future products that will be assembled at production facilities in Port Elizabeth remain on track, and it will soon break ground on a new 250 million rand ($31 million) pan-African parts distribution center.
