'In GATT we (T)rust', a cariacature of GATT working, decorating a wall of the WTO headquarters. The WTO replaced the GATT (General Agreement on Tariffs & Trade) in 1995.
The World Trade Organisation has 164 members, and in theory, negotiates and regulates global trade. It is, however, in crisis: New multi-lateral trade negotiations have been stalled for years, while it's principle dispute settlement body, the 'crown jewels' of the WTO and the global trading system, is almost completely blocked.
