兩岸皆已完成WTO入會程序，正式成為WTO會員。WTO因此成為兩岸共同加入的重要國際官方組織，其在WTO中的互動對兩岸關係具有重要意義。加入WTO是否可以改善兩岸關係?兩岸關係是否因此製造出新的互動型態或者因此朝新的方向發展?由於兩岸先前已在APEC中有互動之經驗，本文擬就兩岸之APEC經驗觀察兩岸於WTO可能之互動型態及對兩岸關係之影響。本文將以四種互動型態作為分析之面向:平等會員地位之爭、議題主導權之爭、可從事合作之領域，以及會外互動等，並比較兩岸於此四個面向上的不同以及其對兩岸嫩係之影響。

　　　　　Taiwan and China completed their application procedure for accession to WTO this year, and formally became its members. As an international organization with membership from both sides of the Taiwan Strait, WTO has significant meanings for cross-strait interaction sand relations. Will the interactions in WTO improve the cross-strait relations? Will a new pattern of interactions appear between the two sides or will the cross-strait relations head towards a new direction due to their membership in WTO? Since Taiwan and China are also members of another important international organization, APEC, the experiences in the APEC can be useful references for observing their interactions in WTO. Based on the experiences in the APEC, this article will explore the possible interaction pattern between the two sides in the WTO, and its impacts on cross-strait relations.
