Maybe I can try to address some of that.
On setting prerequisites, when Ms. Nelder-Corvari was here about a week and a half ago, she read a quote from the Prime Minister that I think addressed this question.
On launching and negotiating free trade agreements and why we do it, the fact that the United States may already have a free trade agreement with a trading partner, or has negotiated one and has not yet ratified it, is certainly a consideration when we're considering whether or not to launch or conclude free trade negotiations. It's not necessarily the driving force behind this. There are all kinds of things that go into these considerations as to how we move forward on an FTA. But clearly if our competitors--not just the United States, but the European Union, Japan, Korea, Chile, Mexico, and others--are all negotiating their own preferential agreements with certain key partners, there are commercial considerations we have to take into account with respect to the competitiveness of Canadian businesses in those markets. That's what helps to drive our FTA agenda.
