General Motors Co. agreed to sell its Hummer sport-utility vehicle brand to China's Sichuan Tengzhong Heavy Industrial Machinery Co. and another investor, nine days after an accord to unload the Saturn unit collapsed. Tengzhong intends to buy Hummer through an investment group in which it will hold 80 percent, and Suolang Duoji will hold the rest, the companies said in a statement on GM's website. Duoji's holdings include Hong Kong-based Lumena Resources Corp. Hummer will remain based in southeastern Michigan. It will begin operations with about 100 to 150 people, CEO Jim Taylor said. The company plans to continue contracting with GM for vehicle production from Mishawaka, Indiana, and Shreveport, Louisiana, for two to three years.
