Trading in the shares of SAIC Motor Corp, China's top car maker, will remain suspended for another five working days from Monday, the company said in a filing with the Shanghai Stock Exchange on Friday.

Trading in SAIC Motor has been halted since Feb. 14 after its holding company, state-owned SAIC Group, said it was working on a major plan involving SAIC.

SAIC Motor manufactures Buick, Chevrolet, Cadillac and Volkswagen brands in China through tie-ups with General Motors (GM.N) and VW (VOWG.DE).

Chinese media reported a week ago that SAIC Group plans to inject additional assets into its listed subsidiaries as it finalises its move to float all of its auto-related operations.
