Answer: to protect domestic producers and expand exports to new markets
Step-by-step explanation:
In the decade following the end of World War I, the United States aimed to protect domestic producers and expand exports to new markets. The high tariffs policy that had defined its trade administration since the Civil War were renewed. Tariffs were established to relieve domestic industries, but eventually, they became a limit to international economic interaction and trade throughout the late 1920s and early 1930s.
