From the Document: "In early 2018, the Trump Administration--citing concerns over national security and unfair trade practices--imposed increased tariffs on certain imported products in general and on U.S. imports from China in particular. Several of the affected foreign trading partners (including China) responded to the U.S. tariffs with their own retaliatory tariffs targeting various U.S. products, especially agricultural commodities. On July 24, 2018, Secretary of Agriculture Sonny Perdue announced that the U.S. Department of Agriculture (USDA) would be taking several temporary actions to assist farmers in response to trade damage from what the Administration has characterized as 'unjustified retaliation.'"
