Reuters reports that GM sales in China have fallen since the country tightened credit lending to help slow consumption earlier this year. The report cited remarks made by Executive Vice President Asia Pacific Troy Clarke on Monday.

"If you look at the sales figures, it has affected the whole industry, maybe our sales even a little more than the industry's," Clarke reportedly told reporters.

"What was the first six months growth that was 15-16 percent in passenger cars sales, that growth has dropped to 12 percent last month," he said, according to Reuters.
