From the Introduction: "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 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.' Specifically, USDA would authorize up to $12 billion in financial assistance--referred to as the 'trade aid' package--for certain agricultural commodities under Section 5 of the Commodity Credit Corporation (CCC) Charter Act (15 U.S.C. 714c). [...] This report provides background on the trade dispute that triggered the trade-aid package as well as the authority used by USDA to respond to the trade dispute with financial assistance. Then the report describes the three components of the trade-aid package with details on their implementation."
