< The establishment of the ASEAN Free Trade Area (AFTA) violated the Most­ Favoured-Nation (MFN) principle of the WTO. On the other side, the establishment of the AFT A was not prohibited under Article XXIV of the GAIT. The contradictitory between principle of MFN and Article XXIV GATT, which was arised from the establishment of the AFTA could hamper the achievement of the objectives of the WTO.
The problem of this research was studied by normative legal study and the data were
seleected by library research, and than the data were analized by qualitative and comparative methods.
From the data analisys, it could be concluded that eventhough the establishment of the AFT A violated the MFN principle, but the implementation of the AFT A agreement would not hamper the achievement of the objectives of the WTO if the implementation of AFTA agreement didn't lead ASEAN to be exclusive free trade area, but was intended to
be a step toward the implementation of free trade principles through regional agreement.
