I believe Costa Rica has delayed because of the presidential elections the end of this month or perhaps in February. There is no serious opposition to the agreement in Costa Rica, and the characterization in this article that it has "failed" in Costa Rica is wishful thinking.
Costa Rica, the most-developed of the six nations that have signed the Central American Free Trade Agreement with the U.S., is balking at ratifying the accord.
....The reluctance of Central America's oldest democracy has surprised the White House and undermines one of its chief arguments for the pact: that Cafta represents an urgently sought benefit for the impoverished region. Costa Rica's ambivalence and the long delay before it votes may influence undecided votes in Congress. The ambivalence already has allowed the opposition to the trade pact in Costa Rica to gain momentum.
...Costa Rica, though, is holding out because of mounting opposition by trade unions, some farm groups and even some business leaders who say Cafta's intellectual-property clauses are too invasive.
...Rep. Moran, Republican Rep. Dan Burton of Indiana and other lawmakers last week tried to pressure Costa Rica by warning that Congress would eventually cut off existing trade preferences if Costa Rica's legislature didn't approve the Cafta.
