China has issued the draft of a new motor industry policy that, the trade newspaper Automotive News said, appears to curtail sharply the ability of foreign vehicle makers and suppliers operating there to safeguard their proprietary technology and intellectual property. Automotive News said the draft, which began circulating among industry executives late last month, specifies that 50% of all sales in China by 2010 must come from domestic companies that own 100% of the vehicle's technology.
