Globalisation, being a rather general political economic term, not surprisingly has mulltiple definitions. GATT, however, is just a multilateral trade agreement. Technically multilateralism is distinct from globalisation. For example, GATT allowed for preferential trade agreements. At best, such agreements restrict globalisation by allowing for trade discrimination (e.g. Different tariffs between member and non-members such that trade is inefficiently diverted). At worst, given regionalism, it is an open assault on globalisation GATT was supposed to be a stopgap as we waited for the ITO to be formed. This would have had economic development as a core interest, which really is a basic requirement for globalisation (as dynamic comparative advantage is enabled such that trade is maximised)
