WASHINGTON — Congress passed three long-awaited free trade agreements on Wednesday, ending a political standoff that has stretched across two presidencies. The move offered a rare moment of bipartisan accord at a time when Republicans and Democrats are bitterly divided over the role that government ought to play in reviving the sputtering economy.

The approval of the deals with South Korea, Colombia and Panama is a victory for President Obama and proponents of the view that foreign trade can drive America’s economic growth in the face of rising protectionist sentiment in both political parties. They are the first trade agreements to pass Congress since Democrats broke a decade of Republican control in 2007.

All three agreements cleared both chambers with overwhelming Republican support just one day after Senate Republicans prevented action on Mr. Obama’s jobs bill.

The passage of the trade deals is important primarily as a political achievement, and for its foreign policy value in solidifying relationships with strategic allies. The economic benefits are projected to be small. A federal agency estimated in 2007 that the impact on employment would be “negligible” and that the deals would increase gross domestic product by about $14.4 billion, or roughly 0.1 percent.
