The Obama administration has filed a challenge at the World Trade Organization accusing China of unfairly subsidizing its auto and auto-parts industries. Announcing the move during a campaign stop in Ohio, President Obama took a shot at Republican rival Mitt Romney.

President Obama: “He made money investing in companies that uprooted from here and went to China — pioneers. Now, Ohio, you can’t stand up to China when all you’ve done is sent them our jobs. Today, my administration is launching a new action against China, this one against illegal subsidies that encourage companies to ship auto part manufacturing jobs overseas. These are subsidies that directly harm working men and women on the assembly lines in Ohio and Michigan and across the Midwest.”
