In an ad just released on Saturday, President Barack Obama has challenged his Republican presidential opponent Mitt Romney’s promise to become tough on China. The ad said Romney was able to make a fortune by giving U.S. jobs to China. The ad for Obama turns to a report that said a number of businesses supported by Romney’s former firm Bain Capital, moved jobs in the U.S. to India and China to lower costs. The narrator, in a final comment in the ad says that Romney is not the solution, but the problem.

The ads follows the recent two-day, two-state bus tour through Pennsylvania and Ohio recently made by Obama, where he announces plans to file with the World Trade Organization a trade complaint against China for placing unfair duties on over $3 billion worth of automobiles made in the U.S. for export to China. In Ohio, a number of auto plants hire thousands directly for the auto industry.

Romney this past week, as well as previously, accused Obama of not being firm enough on China, saying he would call the Asian nation a manipulator of currency on the day he enters the White House. He also said China does not defend against the theft of intellectual property.

The White House administration said on Friday it has made a big effort in cracking down on unfair trading practices by the Chinese, filing seven cases over trade against Beijing.

The new thirty-second ad opens with Romney during a primary debate for Republicans in 2011. He says, that China is smiling by taking our jobs and much of our future, and he say he does not want it to happen. The narrator responds says that Romney was able to make a fortune by allowing just that to happen.
