Republican presidential contender Jon Huntsman says his opponents' policies would start a trade war with China.
Huntsman, the former ambassador to China, says tough talk and new tariffs aren't the answer. And during Saturday's debate, he told Mitt Romney in Mandarin Chinese that he doesn't understand the situation.
Romney favors placing tariffs on China to combat currency manipulation. And he says China is more afraid of a trade war than America.
Romney also criticized Huntsman for serving as President Barack Obama's ambassador to China, while Romney said he was helping elect Republicans back home.
