U.S. President-elect Donald Trump has signaled in an interview that his incoming government may break with the policy of maintaining a strong dollar.

"Our companies can't compete with (China) now because our currency is too strong. And it's killing us," Trump said in an interview with The Wall Street Journal that was published Tuesday.

Trump also said the United States might need to "get the dollar down" if a large-scale tax cut proposed by him drives it higher. "Having a strong dollar has certain advantages, but it has a lot of disadvantages," he said.
