Yes, it is contentious, and the actual discussion is more in the nature of yes, we recognize there are developed countries and there are developing countries, and we're not necessarily arguing with that distinction. Where the debate more recently has been is that there are significant differences between or among developing countries. There are very advanced, very large economies in some developing countries. Other developing countries are very small in economic terms, have little influence and are in a much different situation, without the same kinds of advantages that others have.
The challenge is, how do we differentiate among developing countries in the kinds of obligations we would expect them to take on?
