For November alone, GM sold 260,018 vehicles in China, up 9.7 percent from 2011.
China's overall auto sales growth slowed last year after the government scrapped purchasing incentives and limited car numbers to ease traffic congestion and cutpollution.
In 2011 sales rose just 2.5 percent to 18.51 million units, compared with an increase of more than 32 percent in 2010, but growth has recovered slightly this year.
Nonetheless foreign manufacturers have bucked the slowdown with stronger brand recognition and perceptions of better quality among domestic consumers, although Japanese brands have been hurt by a territorial dispute between Beijing and Tokyo.
GM said last week that one of its Chinese joint ventures will invest 6.6 billion yuan ($1.1 billion) in a new plant to meet growing demand for commercial vehicles.
The venture between GM and Chinese partners SAIC Motor and Wuling Motors aims to open the 400,000-vehicle-a-year plant in the southwestern metropolis of Chongqing in 2015.
