I thought that the WTO was a fairly well-known organisation.
As far as I was aware, the EU belongs to the WTO as a bloc but each country in the EU belongs on an individual basis as well.
Membership
Members and observers
The WTO has over 160 members representing 98 per cent of world trade. Over 20 countries are seeking to join the WTO.
Accessions
To join the WTO, a government has to bring its economic and trade policies in line with WTO rules and negotiate its terms of entry with the WTO membership.
Services trade
Ranging from architecture to voice-mail telecommunications and to space transport, services are the largest and most dynamic component of both developed and developing country economies. Important in their own right, they also serve as crucial inputs into the production of most goods. Their inclusion in the Uruguay Round of trade negotiations led to the General Agreement on Trade in Services (GATS). Since January 2000, they have become the subject of multilateral trade negotiations.

It is based in Geneva.
I do not understand the negative remarks about the WTO.
