On March 15, 2012, the United States entered a trade agreement with Korea. Now, the United States can sell "Made in America" goods, services, and agricultural products to Korean customers. With the reduction of Korean tariffs, this agreement will add about $10 to $12 billion to U.S. Domestic Gross Product and about $10 million to annual merchandise exports to Korea.

The agreement also helped to solidify the two countries' long lasting alliance.
