One minute after midnight the US increased tariffs on $200 billion worth of Chinese exports to 25 percent from 10 percent.
Meanwhile, data showed US goods trade deficit with China, a focus of the Trump administration's "America First" agenda, dropped to a five-year low in March amid a surge in exports, including soybeans.
