Shanghai General Motors Corp. recorded a 59% jump in sales volume in June from a year earlier, said a senior executive of the passenger vehicle joint venture between General Motors Corp. (GM) and SAIC Motor Corp. (600104.SH) Wednesday.

Ding Lei, vice president of SAIC Motor and managing director of Shanghai GM, said that the sales volume gains in June built on the year-on-year growth of 28% recorded in April and 50% in May.

Ding, who was speaking at an event in the southern city of Guangzhou to mark the launch of the new Buick LaCrosse, didn't provide sales figures.

The strong sales in China last month came despite GM's bankruptcy protection filing in the U.S. In early June, GM said its overseas operations were not included in the filing.

GM's other joint venture in China is a commercial vehicle tie-up with Wuling Automobile Co. and SAIC called SAIC-GM-Wuling Automobile Co.

GM's sales in China overall rose 62% in June from a year earlier to 143,294 units.
