In the year since the U.S.-Colombia Free Trade Agreement has been in effect, Colombian exports to the United States have ticked up only marginally, but U.S. exports to Colombia have climbed by 20 percent.

While the results were disappointing for some in Colombia they were also to be expected: Many Colombian products already entered the U.S. market duty-free, and falling commodity prices have sapped trade.

“A very high share of Colombian exports to the United States are commodities,” said Acting U.S. Secretary of Commerce Rebecca Blank, who was in Colombia on Wednesday, the first anniversary of the trade pact. “And we all know the free trade agreement doesn’t have any effect on prices that are set out by world commodity markets.”
