One day before the final presidential debate, Senator Marco Rubio, R-Fla., an ardent Mitt Romney supporter, said he disagrees with the GOP presidential candidate’s promise to label China a currency manipulator on his first day in office. On CBS’ "Face the Nation" Sunday, Rubio said he feared this could lead to a trade war. [Rubio’s comments from ‘Face the Nation’ on Sunday are below:]( > RUBIO: I agree with Mitt Romney that China is a currency manipulator. I believe that a trade war is not the best way to approach it and I think that you label them a currency manipulator that’s what it may result. It will hurt American businesses. But I understand his frustration. We may have to do what governor Romney is saying. We may have to label them a currency manipulator but the ideal way to deal with it because we both have a lot to lose here. China has a lot to lose here too in a trade war. It wouldn’t be good for either one of our economies. So hopefully we can avoid that. It may come to that. But I hope we can avoid that. [ A Center for American Progress Action Fund report published in March 2012 came to a similar conclusion [PDF]:]( > Romney says he will label China a currency manipulator on Day 1 of his administration. But he does not say what he will do on Day 2. Declaring China a manipulator is a symbolically hostile gesture, coming as it would before he will have ever met or spoken to any Chinese leader. And yet what this designation requires is entering into talks with Beijing, made all the more difficult by the declaration itself. […] > > Not only is the approach needlessly antagonistic, it is also ineffective. The last thing China’s leaders will do is invite criticism from their own nationalist base by bowing to a hostile, unilateral American demand — even though a more appropriately valued currency will benefit the Chinese economy over the long run. In July 2012, Rubio also made national headlines when he criticized [Romney for supporting arming Syrian rebels.]( Rubio also had tough comments for President Obama on Sunday. "The president has no plans for the next four years," Rubio said on "Face the Nation" Sunday. "Tomorrow is his last chance to tell us what he’s going to do in the next four years."
