General Motors just issued sales figures for China, and the news of lower volumes comes with warnings of even lower ones down the road.

Including its joint ventures in the country, like with SAIC and Guangxi Automobile Group, GM sold 3.09 million vehicles in China in 2019. That's down from 15 percent from 3.65 million in 2018, and a sharp decline from the 4.04 million units GM sold the year before. The drop was nearly across the board, with the low-cost Baojun brand down by 27.6 percent, Wuling down 5.0 percent, Chevrolet sliding 20.1 percent, and Buick down 16.7 percent. Though Cadillac saw sales increase 3.9 percent to an all-time high of 213,717 units as a highlight on the sales sheet.

"We expect the market downturn to continue in 2020, and anticipate ongoing headwinds in our China business," said GM VP for China Matt Tsien. "During the downturn, we are focused on bolstering our product lineup and improving cost efficiency to position our company for strong performance in China over the long term," he added. The industry-wide downturn in year-over-year sales has been attributed to a declining economy in the country as well as increasing emissions rules.

Tops for GM was the Wuling brand, hitting just over 1 million sales in 2019. Buick delivered 850,007 vehicles, and Chevrolet hit 418,000. GM says it is on track to finish introducing 10 NEVs in China between 2016 and 2020, including the new Chevrolet Menlo, two Baojun models, and a new Wuling.
