Great Wall Motor, China’s largest privately-held maker of sport-utility vehicles, has called off its collaboration with beleaguered US auto giant Chrysler, the South China Morning Post reported, citing state media. The Chinese company’s chairman Wang Fengying told China Business News it would put off its planned cooperation with Chrysler due to "changes in the two carmakers that deter them from making substantial decisions." Chrysler and Great Wall in July of 2007 had announced they would collaborate in several key areas including distribution, component manufacturing and technology sharing. Great Wall will now focus on making passenger cars under its own brand. This marks the second setback for Chrysler in recent months. Chery Automobile announced in December that it had stopped working with the US carmaker due to differing priorities and business directions.
