And two fast-growing developing economies just became a lot more enticing.
I'm talking about Colombia and South Korea - both of which just signed free trade agreements (FTAs) with the United States.
Both treaties date back to the last days of the Bush administration - when bilateral trade deals were fashionable - but had gotten hung up in Congress.
To some extent, free trade agreements merely deflect trade from other paths. However, since the EU has signed a trade deal with South Korea and is negotiating one with Colombia, there are both defensive and trade-building reasons for these deals.
South Korea is a trillion-dollar economy and one of the United States' most important trading partners, with two-way trade totaling $74 billion in 2008. And Colombia's potential as a trading partner is enhanced by its geographical position - close to both the East and West Coast U.S. markets.
Both countries are growing quite fast. In fact, Colombia is expected to clock growth of more than 5% in 2011 and 2012.
The Biggest BeneficiariesThe South Korean deal offers the most potential to U.S. exporters, as the deal is expected to add about $10 billion to U.S. exports and gross domestic product (GDP).
U.S. exporters of agricultural products, which are projected to double from their current $2.8 billion, will be the primary beneficiaries. However, U.S. auto manufacturers and banks will also have a chance to break into the market.
On the other side, Korean exporters of cars, trucks and computer equipment will benefit from better access to the U.S. market.
Colombia has a thriving agricultural sector, but U.S. meat exports should jump significantly. Pork exports, for example, are forecast to grow 72%. IT companies and chemicals producers also will gain improved access to the Colombian market. But the greatest potential will be unlocked in the heavy equipment sector, as Colombia races to develop its mineral resources.
Reduced sanitary inspection barriers will improve the trade flow both ways. That will increase demand for Colombian coffee and flowers. But the big breakthrough will be in Colombia's energy sector, as the country's oil is an increasingly important export to the United States.
Now let's take a look at some of the specific companies that will cash in on these deals.
