東協因受限於國家體質的脆弱性，後冷戰時期當亞太安全互賴性深化後，東協必需借助外力建構國家暨區域安全，但本身具備的經濟與社會發展基礎條件不足，因此與東協以外的國家發展合作關係，成為落實綜合性安全概念的重要一環。與東亞各國建立對話夥伴關係，發展合作關係即為一重要策略，迄今東協共有十個對話夥伴。其中美、日、歐盟等先進國家早就與東協發展經濟與科技轉移等合作關係。冷戰結束後所建立的對話夥伴關係則包括南韓(1991)、俄羅斯(1993)以及中共(1993)。 本文以建構理論探討東協安全概念的轉變，針對東協與大國安全關係，就不同歷史時期的互動關係，進行有系統的研究分析。東協與大國安全合作的思維，至少歷經三階段：(1)1967-1989為冷戰時期美國主導東亞安全，東協雖與大國發展合作關係，然美國為主要角色，此時期的合作關係多屬軍事與政治外交領域者；(2)1989-2002，此時期為「中美雙元」結構。前半段期間為東協開始與東協改變冷戰關係，1997/1998年東南亞歷經亞洲金融風暴，中國大力協助並允諾人民幣不貶值，東南亞自主性日益增長，加速與各大國關係。(3)2002迄今，為東協全面推動三角或多邊主義的安全合作。 本文討論東協最重要的大國關係，如東協與美、日、中、印度、南韓的互動關係，並由台灣觀點出發，討論台灣於東南亞整合潮流中的因應之道。

Having been maintaining its weak nature for 4 decades, ASEAN had to continuously promote its national and regional security after the cold war era. In the past four decades, ASEAN member states have had different styles related to their economic and political developments. ASEAN wants to expand its dialogue partners, so far it has had 10 dialogue partners-include, China, Japan, South Korea, North Korea, EU, India, Australia, New Zealand …etc. In terms of regional security cooperation among ASEAN and the great powers, it is useful to divide the last 40 years into three periods as follows: (1)1967-1989 characterized by U.S. domination in the region and security cooperation between ASEAN and the U.S as mainly political and military; (2)1989-2002 was the so called「Sino-US bipolar system」, during the first half of which there was still hostility among China and certain ASEAN states. After the 1997/8 Asian financial crisis, bilateral relations between China and ASEAN notably enhanced as China adopted "good neighbor policy" towards ASEAN; (3) from 2002: Not only have ASEAN developed good relations with China, they are also seeking to promote multilateral relations with other big powers like India, EU and Russia. This paper will firstly analyze multilateral relations among ASEAN and great powers in this region. Secondly, in terms of regional integration, ASEAN wants to play more and more dominant and important role. Finally, this paper suggests Taiwan should adopt some strategies what could avoid losing Taiwan's political and economic influence in the Asia Pacific Region.
