In the past 20 years the United States has entered into several "free trade agreements." The commonality of these free trade agreement has been making it easier for foreign companies to sell their goods in the United States (imports) and for American companies to sell their goods overseas (exports).
In your initial post, summarize the key points of specific trade agreement the United States has entered into in the last 25 years. Be sure to include the other counties involved and what kinds of trade restrictions and/or tariffs were changed as a result of that agreement. Include citations at the end of your post (should be easy to find info on trade agreements on the web).
