My post wasn't about China, per se, but unenforceability.  Substitute any country for China and the point is made.  I could have said "US" and, while GATT XX sanctions would hurt, not many countries are willing to forego this market.  If I said "Germany", again some trade sanctions would hurt but it is not clear that, as a member of the EU, those sanctions would be enforceable; that is even supposing that GATT XX was included in PARIS - it's not.

I get to visit China a couple of times a year, and what they accomplish is truly impressive - until you realize the cost to freedom.  Perhaps that is a darker reason that "human rights" were omitted from PARIS.
