The U.S.-China trade war initiated by the Trump Administration has had a significant negative impact on U.S. agricultural exports to that country. In response, some U.S. senators and representatives have been pressing for relaxation of U.S. restrictions on such exports to Cuba. These advocates include Senators Heidi Heitkamp (Dem., ND), Amy Klobuchar (Dem., MN) and Tine Smith (Dem., MN) and Representatives Collin Peterson (Dem., MN) and Tom Emmer, (Rep., MN). 
In addition, a bipartisan group of over 60 agricultural associations, businesses and elected officials from 17 states have urged the two congressional agriculture committees to include in the pending farm bills a provision to remove restrictions on private financing of U.S. agricultural exports to the island. 
This week Cuba President Miguel Diaz-Canel in New York City for a meeting of the U.N. General Assembly met separately with a bipartisan and bicameral group of Members of the U.S. Congress, including Sen. Ron Wyden (Dem., OR), Rep. Karen Bass (Dem., CA), Rep. Kathy Castor (Dem., FL), Rep. Robin Kelly (Dem., IL) Rep. Gregory Meeks (Dem., NY) and Rep. Roger Marshall (Rep., KA). Rep. Marshall told AG NET that the U.S. “can and should be Cuba’s number one supplier of commodities like sorghum, soy, wheat, and corn.”
But legislation to expand such exports by allowing credit sales to Cuba did not make it into the pending farm bills in both houses of the Congress, and most observers and participants think chances are nil of such a provision being added. And Senator Heitkamp’s provision in the Senate bill to allow the U.S. Department of Agriculture to use federal funds to develop the Cuban market could easily be cut from the bill in a conference committee.
The reason has more to do with politics than economics, according to Ted Piccone, a specialist in Latin American issues at the Brookings Institution. “It basically comes down to domestic politics in Florida,” Piccone said.
