"American growers of soybean, which is the most-imported U.S. commodity in China, are expected to be hit hardest by the trade war. In 2017, China imported from the U.S. about 33 million tons of soybeans, which are used to feed livestock and make cooking oil. If China can find another source for its soybeans, such as Brazil, the U.S. could see economic losses of about $1.7 billion and $3.3 billion a year, according to Purdue University."
