DETROIT (AP) — General Motors and its joint venture partners say they will build a third factory complex in China to keep pace with rising sales.

GM China, SAIC and Wuling Motors expect to start construction on the plant in the Chongqing municipality early in 2013, with the $1 billion first phase opening in 2015. Eventually the plant will be able to build 400,000 vehicles and engines per year, the company said in a statement Wednesday.
