Obama tackles China on car trade
President Barack Obama lodged an unfair-trade complaint against China and immediately used it as a wedge against Republican challenger Mitt Romney, whose beleaguered campaign hit another pothole even it tried to regroup from a shaky few weeks.
Mr Obama told voters in Ohio, where the car industry is important, of his administration's new push for the World Trade Organisation to sanction China for subsidising exports of vehicles and car parts - and costing American jobs.
