General Motor's Buick sold more than 1 million units in global sales this year through September, thanks largely to the 860,384 vehicles sold in China, the automaker said on Tuesday.

Buick made the earliest date in history as it sold a total of 1,046,746 vehicles in the first nine months of 2016, up 23 percent compared with that of in 2015, Fortune reported.

With a global sale increase of more than 200,000 during the nine-month total, China accounts for 82 percent of Buick's total sales, or five times as much as its U.S. sales, according to the Detroit Free Press.

Buick is ready for its fourth consecutive record year of global sales, GM said.

China is Buick's biggest market. In the first half of the year, the home of the world's largest consumer accounted for 38 percent of all GM's sales. Furthermore, in 2015, GM accounts for 14.9 percent of the Chinese market.

One of the highly in-demand model is the Buick Envision, a small SUV, which was released in the U.S. in July. So far, U.S. dealers have sold 6,100 units, while China sold 140,000, USA Today noted.

GM announced it will stop its Verano sedan distribution in the U.S. and will introduce a new sedan and hatchback version in China. Other Buick models available in the Chinese market, but not in the U.S., include the Excelle XT, Excelle GT, and GL8 minivan.

Meanwhile, Fortune noted the head of GM China earlier this year that Chinese consumers' continued preference for luxury brands could help make that country the largest global market for Cadillac over the next five or 10 years.
