SHANGHAI - China's Commerce Ministry has not rejected heavy equipment maker Tengzhong's planned purchase of GM's Hummer unit, but has asked for more information on the deal, a source familiar with the matter said on Tuesday, according to Reuters.

Legal Evening News, a semi-official newspaper, reported on Monday that the ministry had turned back Tengzhong's application for the deal because it was lacking in detail.

Sichuan Tengzhong Heavy Industrial Machinery, a little-known Chinese firm, raised eyebrows when it unveiled plans three months ago to take over the Hummer brand.
