On the campaign trail, Republican hopefuls Rick Santorum and Mitt Romney invoked the visit by Chinese Vice President Xi Jinping on Thursday to vow changes to U.S. policy toward China. Both Santorum and Romney made the comments while campaigning in Michigan.

Rick Santorum: “You know, if we’re going to point the finger at other countries, then we need to look at what we do here in America when it comes to currencies and what we’re doing with the value of the dollar in this country. Let’s have the market do it. And if you do, I am confident that the American worker and American companies can compete with anybody around the world.”

Mitt Romney: “If I’m president of the United States, I will finally take China to the carpet and say, 'Look, you guys, I'm going to label you a currency manipulator and apply tariffs, unless you stop those practices.’ We will not let China continue to steal jobs from the United States of America.”
