Yes, each of the three countries also has to ratify the agreement in accordance with its legislation. The latest reports indicate that Greece has completed the process and is ready to ratify the treaty. As for Colombia, I am told that the Senate approved the treaty at the end of September. It is now in the hands of that country's House of Representatives, which will debate the matter. In Turkey's case, it has gone through the foreign affairs committee in the Turkish Parliament and will be studied by the general assembly. Chances are good that these two countries will be able to ratify the agreement by the end of the year.
On October 4th, 2010. See this statement in context.
