I think this will be a difficult negotiation to conclude, particularly as the number of countries involved expand. The United States has some very ambitious, aggressive demands, but at the same time it's very protective of its own sensitivities in many areas. I could see that in, for example, their proposals on intellectual property rights and drug pricing where they've carved out Medicaid and other things.
Another factor is that there are actually parallel negotiations for regional economic integration in the Asia-Pacific region that don't involve the United States but involve China and many of the other partners. By all reports these are much more flexible and sensitive or open to various domestic sensitivities that the countries involved have. So there's an alternative that people can move to if they feel they're being shaken down too much by the United States.
