It could be something as simple as a side agreement of what method of production restrictions all parties will in fact respect whether or not they are subject to successful challenge with countervailing duties permitted within the WTO.

After all, at its core, the WTO system works on a civil court style system - if a successful complaint is brought, the penalty is that all affected parties can impose countervailing duties. If there are certain circumstances where a large number of countries agree to refrain from imposing those countervailing duties, that de-claws the WTO.

Indeed, the G-77 could get an agreement on a non-toxic next round of the WTO, except within the bounds of that side agreement - and the right agreement could pull in a large swathe of sub-Saharan Africa and South America.

Get a large enough swathe of Sub-Saharan Africa and South America in that side agreement together with the EU, and it might be a tough decision for China to make whether join it and make for effective over-ride of the standing WTO interpretation of its rules that allows "no method of production regulation allowed" to override the dead letter public benefit provisions.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
