WASHINGTON (Reuters) - U.S. Commerce Secretary Wilbur Ross said he told Mexican Economy Secretary Graciela Marquez in a meeting on Monday that Mexico must do more to help the United States address illegal immigration.

Ross said in a statement he discussed the U.S. plan to hit Mexico with a 5% tariff next week on goods imported into the United States unless Mexico takes steps to curtail the flow of migrants.
