China, the world’s biggest soybean importer, has bought a record amount of soybeans from Russia while canceling multiple soy shipments from the U.S. in retaliation to the Trump administration's tariffs on Chinese goods, reports the Wall Street Journal.

Why it matters: American farmers are heavily dependent on soybean production as a source of revenue. In 2016, soybeans accounted for 12% of exports from the U.S. to China. But that stream is now dissipating with China using subsidies incentivizing their own farmers to cut reliance on U.S. soybeans. Go deeper: Soybeans are a political ground zero in Trump's trade war with China.
