China's booming automotive industry has come with a price in that country - an alarming traffic fatality rate. But that's an opportunity for U.S. safety suppliers such as TRW Automotive Holdings Corp. and Key Safety Systems to export their expertise and business to China , Chinese government officials and industry analysts said last week. Livonia-based TRW, for example, said its revenue growth in China surpasses auto production growth because of the demand for safety products such as anti-lock brakes and air bags. Chinese officials - who were in Detroit last week for an automotive conference at Wayne State University - said the government wants to improve the safety rating of Chinese-made cars and reduce traffic deaths.
