There certainly was some discussion of those issues when the agenda for the negotiations was first agreed to in Doha in 2001. At that time, at the end of the day, it was decided that neither labour nor environmental standards issues would be included as part of the negotiations, so that has remained the same to this point. That really established a mandate for all countries for the negotiations.
This is part of the debate in the U.S. in relation to trade promotion authority. Many in the U.S. want the U.S. to adopt labour and environmental standards in their bilateral agreements, but they recognize it's not going to be possible at the WTO.
One area that we can get at least some of the environmental issues is with respect to the green box provisions of the agreement on agriculture, which we are trying to clarify and in some cases tighten in order that environmental programs truly do benefit the environment.
