Donald Trump said on Tuesday that countries which "don’t open up" to U.S. trade will face a "substantial tariff," renewing his protectionist message amid continuing tensions with Beijing. Trump added that the United States would be "fighting China in a very friendly fashion," asserting that Washington is "way ahead" and that China "is going to be very far behind." The remarks follow the 145% U.S. tariff on Chinese goods that took effect in April and come as the two nations remain locked in a broad economic and technological rivalry.
