The motor industry is getting swept up in the tide of manufacturers heading to China, which is threatening to shift some of the Mexican jobs provided by US parts maker Delphi Corporation, a company official said, according to Dow Jones. The news agency said that Delphi, the world's biggest automotive parts maker, employs more than 70,000 in Mexico, making it the country's largest private-sector employer, and spent $US1.64 billion in Mexico last year, more than half of which went toward wages and benefits.
