本次國際會議以殖民主義、軍事主義與遷移為主要分析視角，探討東亞地區領域性的歷史變動與當代轉化。會議並不將「東亞」視為一個界線清楚、內涵固定的地理單元，而是將其理解為一個在多重力量交錯之中持續生成的空間：一方面，它深受帝國、民族國家、區域安全體系以及資本主義拓邊過程所形塑的殖民與後殖民空間秩序所影響；另一方面，它又不斷溢出並超越這些既有框架。從帝國擴張與戰時佔領，到冷戰時期的分斷格局，再到後冷戰的重新調整，東亞的領域體制始終在法律、經濟、軍事與物流等多重基礎設施的運作之中被建構與重組，同時也透過各種知識生產的方式不斷被理解與再現。

在這些歷史過程背後，可以看到三股彼此牽動的力量。殖民主義一方面推動資源的開採與掠奪，另一方面也建立起關於種族、空間與法制的多重分類與治理秩序。軍事主義及其延伸的軍事化過程，則透過基地部署、防禦設施、安全體制與治外法權等安排，逐步鞏固對空間的掌控，並使特定的政治邏輯內化為日常運作的一部分。至於遷移——無論是被迫還是自主，也不僅限於人類——則不斷衝擊既有邊界，重新界定歸屬，並在反覆移動之中改變領域運作的方式。本次會議所關注的，是這三股力量如何在相互交織與拉扯之中，共同塑造出此一區域的空間樣態——既體現在具體可見的物質層面，也存在於人們對空間的想像之中。

會議亦特別關注各類型的「危機時刻」——無論是生態、政治或經濟層面的斷裂——如何打亂既有的空間秩序，並促使其重新調整。在這些關鍵時刻，關於主權、正當性與移動的各種主張往往重新浮現，甚至彼此競逐。也正是在這些斷裂之中，殖民主義、軍事主義與遷移之間的糾纏關係變得格外清晰，進而催生出充滿爭議的空間形態與持續演變的領域實踐。

本次會議匯集歷史學、地理學、人類學、政治理論及相關領域的研究者，期望從多重學科視角出發，深入討論東亞的空間政治，以及帝國、暴力與移動所留下的歷史遺緒——這些遺緒不僅仍在延續，更不斷介入並重塑當代的區域現實。

This international conference explores the shifting dynamics of territoriality in East Asia through the lenses of colonialism, militarism, and migration. Rather than treating “East Asia” as a bounded geographic unit, it approaches the region as a space simultaneously shaped by and exceeding the colonial and postcolonial cartographies instituted by empires, nation-states, regional security alliances, and capitalist frontierization. From imperial expansion and wartime occupation to Cold War divisions and post–Cold War realignments, territorial regimes in East Asia have been continually constituted and reconfigured through diverse infrastructures—legal, economic, military, and logistical—as well as through various modes of knowledge production.

Three interconnected forces have been central to these processes. Colonialism has instituted overlapping orders of things—racial, spatial, and juridical—alongside extractive economies. Militarism and militarization—through bases, fortifications, security regimes, and practices of extra-territoriality—have entrenched forms of spatial control and ideological normalization. Migration, both forced and spontaneous, human and non-human, has persistently unsettled, negotiated, and redefined borders, belonging, and territorial logics. This conference examines how these forces, operating together and in tension, have configured both the material and imaginary geographies of the region.

Particular attention is given to moments of crisis—ecological, political, or economic—that disrupt and recalibrate these spatial orders, generating new claims to sovereignty, legitimacy, and mobility. It is often at such moments of rupture that the entanglements of colonialism, militarism, and migration become most visible, giving rise to contested geographies and evolving territorial practices.

Bringing together scholars from history, geography, anthropology, political theory, and related fields, the conference invites critical engagement with the spatial politics of East Asia and the enduring—and still unfolding—legacies of empire, violence, and mobility.
