國際空間及國際參與是我國民眾及政府關注的重大議題。由1993年開始，我國政府採取不同策略以重新參與聯合國，然其成效則受到國際組織本身、國際與兩岸因素及我國國內因素所限制。近年我國改以「有意義參與」作為策略，自2009年開始，我國得以參與世界衛生大會，並於2013年以主席特邀貴賓的身分，出席國際民航組織大會。 我國國際地位處境特殊，美國對於我所參與的各項國際組織之支持非常重要。本文以我國本次獲邀參與國際民航組織大會作為個案，分析我國參與的策略以及美國作為促成者的角色，並以此探究未來我國參與不以國家身分為先決條件的政府間國際組織時可以採行之策略。

International space and participation are salient issues to the gen-eral public and government in Taiwan. Taiwan has sought to rejoin the United Nations (UN) with different approaches since 1993, but these efforts have yet to result in Taiwan’s full participation due to the con-straints put forth by the Charter of the UN, complicated relations be-tween Taiwan and other parties including China, and Taiwan’s do-mestic politics. In recent years, Taiwan shifted its strategy to “mean-ingful participation,” and the government is willing to be flexible on the conditions under which Taiwan participates in inter-governmental organizations. Since 2009 Taiwan has continued its attendance to the World Health Assembly (WHA), and was invited as a guest to the General Assembly of the International Civil Aviation Organization (ICAO) in 2013. Due to Taiwan’s unique status in world politics, support from the U.S. is crucial to Taiwan’s participation in international organizations. Based upon the case study on Taiwan’s participation in ICAO in 2013, this paper argues that the U.S. as a facilitator helped Taiwan garner support from the international community and resulted in China’s acqui- escence. Taiwan’s strategy for future participation in international or-ganizations for which statehood is not a prerequisite is further discussed.
