任期/ 2021.3.1至2025.8.31

台灣身分/ 2002年以「台澎金馬個別關稅領域」正式加入

主要職能是調解成員國之間的貿易紛爭，促進全球自由貿易，是當代最重要的國際經濟組織之一。入會門檻是必須降低進口關稅，或是開放某些服務貿易。但同時間，入會後也可以享有其他國家提供的關稅減免，對以出口為導向的台灣相當重要。是台灣極少數以正式成員國身分加入的國際組織。
但近幾年，由於國際局勢變遷，WTO的功能性逐漸被區域經濟組織與自由貿易協定削弱，除了一些貿易訴訟案之外，很少看到WTO相關消息。

Year of Establishment: 1995

Taiwan status: officially joined the WTO as the Separate Customs Territory of Taiwan, Penghu, Kinmen and Matsu in 2002

As one of the most important international economic organizations, one of the main functions of the WTO is resolving trade disputes between member states and facilitating global free trade. The accession threshold requirements include concessions on import tariffs or opening up access to certain trade in services. This also means that accession to the WTO guarantees access to tariff concessions made by other countries. This is crucial to export-oriented Taiwan. The WTO is one of the very few international organizations in which Taiwan is a full member state. 

However, in recent years, due to changing international dynamics, regional economic organizations and free trade agreements have gradually chipped away at the WTO’s role, which is now mostly only associated with some trade litigation.
