Former Massachusetts Gov. Mitt Romney says he will confront China for undervaluing its currency and hurting American jobs.

Romney says if he's elected he'll identify China as a currency manipulator and bring action with the World Trade Organization.

Romney says that if the U.S. isn't willing to stand up to China, "you'll get run over by China." He says the U.S. needs to "call cheating for what it is."

Former Utah Gov. Jon Huntsman cautions that the tough tactics could lead to a trade war with China, which would hurt small businesses.

Huntsman is the former U.S. ambassador to China. He says the nation has no choice but to find common ground with China.

The comments were made during the Bloomberg-Washington Post presidential primary debate held at Dartmouth College.
