I think that had to do with our strategy around negotiations to a large degree, to be very candid. I don't think it's impossible. Had we chosen to do so, we wouldn't have achieved the same success as the U.S. in their negotiations.
There has been a change in thinking in the U.S., because they have evolved along the same path we have in negotiating a free trade agreement. They have seen the same inherent weakness we have encountered in dealing with labour and environmental provisions of trade agreements.
I think they fundamentally believe that incorporating those two elements within the core of the agreement gives equal recognition that labour and environment matters will be treated with the same weight and commitment as public policy. More importantly, it sends a clear message to the countries we're negotiating with that they have the same reciprocal commitment.
In the absence of failing to give a clear commitment to enforce their labour and environmental provisions, they could suffer some significant penalties under the agreement. That certainly brings it into a better balance. The ultimate objective is to improve the conditions in which labour and the environment will be treated in both countries.
From our perspective with our trade negotiators, this is just a question of tactics. We have chosen not to go that route. Some would argue that's using a sledgehammer to deal with the issue. But I believe, to be fair, that despite our prodding and encouragement we haven't yet achieved the degree of success we are claiming for labour and environment within our trade agreements with the countries we've been negotiating with.
