Guizhou may be one of China's poorest and least developed provinces. But the flip side is an environment so pristine that Pres Xi Jinping recently joked its air should be bottled. Now, Taiwan's Foxconn Technology Group, the world's largest consumer electronics producer, with more than a million employees working in 30-some industrial parks across China, has set its sights on backward but beautiful Guizhou. The maker of Apple's iPad and iPhone and Hewlett-Packard servers is building an industrial park in China's southwest, seemingly worlds away from its massive and gritty Shenzhen manufacturing base, that aims to be state of the art in energy efficiency and environmental friendliness. Foxconn not surprisingly is facing pressure from its top customers to ensure its production process has fewer environmental costs.
