If I remember it's things like having same standards of animal welfare innabbatoirs (the U.S. Think EU chickens are dirty IIRC).
But it has gone south because it was played badly politically - the heads of the main negotiating countries should apparently have a summit, announce it was crap and announce a new round that will be
- public and open - use a highest standard wins (ie if US rules on X are more stringent than EU then the U.S. Rules are the standard for TIPP) - something else about timelines - I think not setting big deadlines - being more multilateral like WTO
It seems a sensible move and likely to take a lot of the sting out of "rules made behind closed doors, race to the bottom etc"
Contrary views welcomed...
