I'm not aware of any. If you look at all the literature I have seen, and obviously NAFTA is the example that has the longest track record, economic, equality, labour, and trade union rights in all three of the NAFTA signatories countries—Canada, the United States, and Mexico—have in my view gotten worse since we signed NAFTA.
The example of Colombia has been mentioned. Obviously the Colombia agreement was only implemented, if I'm not mistaken, last summer, so we don't really have enough of a track record to connect whatever may be happening in Colombia to the implementation of that agreement.
I would challenge gently those who assert that free trade is bringing growth, prosperity, and certainly equality and justice to Colombia. I have been to Colombia on many occasions, and I have met with President Santos to discuss these issues. It is true that there has been some diminution in the level of violence in Colombia, but it is not true, in my estimation, that the situation for workers and trade unions has improved demonstrably over the last number of years.
