二次世界大戰後，隨著全球事務的複雜化，跨國經濟活動、新科技與網路的發達，加遽了人與人之間的交流與互動，也使得國際間的相互依賴愈來愈加深與頻繁，從而大幅改變國際關係之面貌，致使國與國之間的界線也變得模糊。非政府組織的興起意味著傳統以「國家為國際事務主要成員」的觀點受到質疑與挑戰，當各國治理範疇逐步縮減時，非政府組織卻開始填補了政府在國際活動方面的空缺，在國際社會中快速擴張，因此，在進行國際援助時，若非政府組織與政府之間如能相互協力，應比其中任何一方單打獨鬥更能..

Mainstream IR theories are typically multilateral. However, for any multilateral frame or value to last, bilateral relations must be able to resolve conceivable limitations. Thus, bilateral relations should be intrinsic to IR theorization. We use the United Kingdom in the aftermath of WWII as our case. The UK managed bilateral relations with the United States and China as ways to overcome its decline after the war. The bilateral relations transcend the multilateral frame and value.
