General Motors Co (GM.NYSE) plans to deepen its ties with SAIC Motor (600104.SH), China’s largest automaker, in a move that could expand the partnership beyond its existing relationships in China and India, the Wall Street Journal reported. Sources familiar with the plan said the companies are expected to disclose the expanded cooperation in China on Tuesday, as GM holds its first-ever monthly board meeting in Shanghai. GM also said it has a plan in the works after SAIC completes a restructuring to re-acquire a 1% stake in Shanghai GM, the largest of its 10 joint ventures with the Chinese automaker, once more giving GM 50% ownership. As it was sliding into bankruptcy in 2009, GM sold the 1% stake for US$84.5 million, giving SAIC 51% ownership and majority control of the venture.
