General Motors and its joint ventures delivered over 526,000 vehicles in China in the second quarter this year, up 9 percent from a year earlier, said the United States-based carmaker on Thursday.

The carmaker saw its sales of new energy vehicles hit a record high in the quarter, hitting 115,000 units.

In the same quarter, deliveries of vehicles bearing its Chevrolet brand exceeded 48,000 units, up 20 percent year-on-year.

Of them, the Monza remained the best-seller, with sales up 56 percent year-on-year to hit 33,000 units.

GM's premium Cadillac saw even faster growth in the quarter, with over 55,000 delivered, up 51 percent from the same period last year.

The carmaker said it is on track to launch more than 20 new and refreshed models in China this year, over one-third of which will be NEVs.

New products built based on the global Ultium platform and SAIC-GM-Wuling's GSEV platform will roll off the assembly line in the second half this year to further differentiate the carmaker's EV offerings in China, it added.

In an interview late last month, Julian Blissett, executive vice-president of GM and president of GM China, said the company is confident in China's vehicle market, which has been the world's largest since 2009.

"We have every intention of increasing investment and increasing our commitment here in China," he said.
