The tariffs will rise to 25 percent on January 1 of next year.

With the new tariffs, about half of China's imports to the United States are covered by punitive trade measures.
Trump campaigned for the presidency on a pledge to tax imports and rewrite or tear up trade agreements that he said put U.S. companies and workers at a disadvantage.
