Obama from China on two-step proposal

From the press conference following his meeting with Hu Jintao:

“Our aim there, in support of what Prime Minister Rasmussen of Denmark is trying to achieve, is not a partial accord or a political declaration, but rather an accord that covers all of the issues in the negotiations, and one that has immediate operational effect. This kind of comprehensive agreement would be an important step forward in the effort to rally the world around a solution to our climate challenge. And we agreed that each of us would take significant mitigation actions and stand behind these commitments.”

Also, some interesting language in the official Joint Statement that came out of the meeting:

[B]oth sides believe that, while striving for final legal agreement, an agreed outcome at Copenhagen should, based on the principle of common but differentiated responsibilities and respective capabilities, include emission reduction targets of developed countries and nationally appropriate mitigation actions of developing countries.

Which would seem to indicate that both the US and China will have some numbers on the table in Copenhagen.
