As reported by a poker web site:
According to the Tico Time in Costa Rica, the United States and Costa Rica have come to a settlement agreement in regards to the United States pulling out of its World Trade Organization agreement involving online gambling.
As compensation for not allowing online gambling companies based in Costa Rica access to U.S. customers, the United States has offered Costa Rica greater access to other service markets, including research and development, storage, technical testing and analysis.
This is similar to the settlements the United States has reached with Canada, Japan and the European Union in the matter.
Costa Rica's settlement took place after the country had filed for arbitration before the World Trade Organization, when it didn't look like the United States and Costa Rica would be able to find agreeable terms.
"The agreement has been satisfactory for the country," said Foreign Trade Minister Marco Ruiz in a written statement.
I believe that leaves only Antigua negotiating with the U.S. on the GATS withdrawal of concessions.
