Navarro's views on trade are significantly outside the mainstream of economic thought, and are widely considered fringe by other economists. A strong proponent of reducing U.S. trade deficits, Navarro is well known as a critic of Germany and China and has accused both nations of currency manipulation. He has called for increasing the size of the American manufacturing sector, setting high tariffs, and "repatriating global supply chains." He is also a vocal opponent of multilateral free trade agreements such as NAFTA and the Trans-Pacific Partnership Agreement.
