President-elect Donald Trump's pick to lead the U.S. Treasury, Steven Mnuchin, said on Wednesday the administration would make tax reform and trade pact overhauls top priorities in order to achieve a sustained pace of 3 percent to 4 percent economic growth.

The one-time Goldman Sachs banker, together with Wilbur Ross, Trump's nominee for commerce secretary, outlined Trump's economic agenda, including what Mnuchin called the largest tax overhaul since the Ronald Reagan administration, in an interview on CNBC.

Trump, throughout his presidential campaign, pledged to redraw trade deals to win back American jobs. He has threatened Mexico and China with punitive tariffs that some economists have warned could spark a trade war that could potentially roll back decades of liberalization.
