(Reuters) - General Motors Co paid $119 million in September to buy back a 1 percent stake in its joint venture with its top Chinese partner SAIC Motor Corp , which it had given up ahead of its 2009 bankruptcy.

The deal pushed GM's ownership in Shanghai GM back to 50 percent, the U.S. automaker disclosed in a filing with the U.S. Securities and Exchange Commission on Friday. However, SAIC retains a 51 percent share in the sales side of the business.
