The concept of ensuring access to foreign markets for U.S. agricultural products dates nearly to the founding of the Republic, when Thomas Jefferson was posted to Paris to, in his own words, ensure “the receipt of our whale-oils, salted fish, and salted meats, on favorable terms; the admission of our rice on equal terms with that of Piedmont, Egypt and the Levant; a mitigation of the monopolies of our tobacco by the Farmers-general, and a free admission of our productions into their islands.”
