Nick Schifrin:

There was a document this morning that the so-called sherpas, the diplomats who are negotiating this, had ready for the leaders. This afternoon, the leaders reviewed it.

And the sherpas will go back tonight to talk about some of the disputes. So, a few of those, climate change, there has been an agreement, according the diplomats I have talked to, about an inclusion of the Paris climate accord, but they're still working on the wording there.

Number two, multilateralism, which has been a big dispute between especially Europe and the United States, diplomats told me there's been an agreement on language along the lines of a commitment to working multilaterally on a rules-based order. And those words, rules-based order and multilateralism, had been a red line for the Europeans.

But the big ones, migration, trade and steel, still a dispute. China pushing for language about free trade, the U.S. resisting any criticism of protectionism. Now, that's, of course, the dispute not only in Buenos Aires, but all over the world today.

Already, in order to get to an agreement or try to get to an agreement, this document is down to about three pages. Last year's was 15 pages. So, they're trying to be much more vague.

But, Judy, it just goes to show how difficult consensus is, not only here in Buenos Aires, but all over the world right now.
