Obama will announce during a campaign tour of Ohio on Monday that he is initiating a case against China at the World Trade Organization over allegedly illegal subsidies for automobiles and auto parts, the official said.

The move allows Obama to take a stand on China and advance the interests of a major job-providing industry in a state that could tip the balance in a close election. His opponent,Mitt Romney, has attacked Obama for what he says is an overly cautious approach to pressuring China into observing international norms for trade, foreign exchange, and patents and trademarks.
