The main differences：

关贸总协定是临时的。从未得到成员立法机构的批准，也未包括创立一个机构的条款。

GATT was ad hoc and provisional. The General Agreement was never ratified in member's parliaments, and it contained no provisions for the creation of an organization.

世界贸易组织及世贸协议是永久性的。作为一个国际组织，世界贸易组织由于成员的立法机构批准了世贸协议，且世贸协议本身描述了世贸的运作方式，因而有了很好的法律基础。

The WTO and its agreements are permanent. As an international organization, the WTO has a sound legal basis because members have ratified the WTO agreements and the agreements themselves describe how the WTO is to function
