Abstract
This paper examines how the distinct regional dynamics of the Cold War era continue to play the most important role in defining the present foreign policy decisions of ASEAN member nations. The essay draws on a comparative case study analysis of the Philippines, Malaysia, and Vietnam to demonstrate the various historical trajectories that have led to a convergent strategy of "hedging" in the face of modern Sino-American strategic conflict. The Philippines, a historic US ally, shows a pattern of oscillation between alignment and autonomy. Malaysia shows a consistent approach to non-alignment and careful balance. Vietnam, a former member of the Eastern Bloc, has been effective in promoting international integration and reconciliation. The analysis contends that, despite their divergent Cold War experiences, all three states now use the ASEAN platform as an essential framework for presenting a unified front on shared regional challenges, particularly the South China Sea disputes, and engaging major powers through multilateral dialogue and consensus-building. The conclusion proposes that the Cold War's legacy provides the necessary historical backdrop for understanding modern Southeast Asian state behavior, while ASEAN serves as the institutional vehicle for converting this historical experience into effective diplomatic practice.
