自 Dittmer 開啟戰略三角的國際政治理論後，三邊戰略探討便成為頗具詮釋力的理論模型。從冷戰時期的「美、蘇、中」戰略三角到近期的其它戰略三角，如「美、中、歐盟」、「美、中、印度」等等，族衍甚繁。 然而在東亞區域間的「美、中、台」戰略三角，隨著「中國崛起」的世界性影響與美國的東亞區域霸權穩定與利益，更使「美、中、台」戰略三角凸顯其重要性與區域霸權穩定或轉移的關鍵。以「美、蘇、中」戰略三角為立論基礎的 Dittmer 戰略三角論，是基於..

Since Lowell Dittmer proposed the theory of strategic triangle, the theory has become a powerful explanatory model that developed various triangles from the US-Soviet Union-China strategic triangle in the Cold War to the other more recent triangles like the US-China-EU and the US-China- India. Among various triangles, the US-China-Taiwan triangle has evolved into a relatively more critical one in terms of its impact on the regional hegemonic stability or shift in East Asia due to the rise of China that is shaking the US hegem..

蒙古位於亞洲內陸，夾處於中、俄兩大強國之間的戰略位置，使其曾長期被兩大強鄰視為領土的邊疆(frontier)。隨著 1991 年蘇聯瓦解，使近代蒙古第一次擁有完整主權。此後，蒙古的對外政策定調為「不結盟、等距離、全方位」，在「第三鄰國」戰略操作及地理條件基礎下，以平衡為原則，執行外交策略。誠然，蒙古如何在兩大強鄰之間求取平衡的生存之道，建構出獨立與靈活的外交及經貿空間，是蒙古確保國家安全的一大課題，也是本文的研究目的。  ..

Mongolia, with its strategic location between China and Russia in the inner Asia, is seen by its powerful neighbors for hundreds of years as a frontier. In 1991, modern Mongolia obtained complete sovereignty for the first time after the disruption of USSR, Hereafter, its foreign policy was principled upon “independence, non-alignment, multi-pillars”. Under the “third neighbor” strategy, Mongolia uses the opportunities endowed from its geography to balance neighboring threats, ensure its national securi..
