The Obama administration is prepared to bring a case against the Chinese government at the World Trade Organization, an official confirms. The Cleveland Plain Dealer has the details: While President Barack Obama travels to Columbus and Cincinnati Monday for campaign appearances, his administration also will ask the World Trade Organization, or WTO, to step up a review of what the White House says are unfair duties that China levies on American-made cars. The case is technically separate from the auto parts case but the administration says it presents another example of China's trade-policy abuse.
