Indian Diaspora in Southeast Asia — Malaysia, Singapore & UPSC Notes (UPSC International Relations)

Study Notes · General Studies · GS II · Indian Diaspora · International Relations

UPSC guide to Indian diaspora in Southeast Asia: Malaysia, Singapore, Myanmar, Indonesia, Thailand, Vietnam, Indo-SE Asia historical links and 2024-26 updates.

Southeast Asia hosts one of the deepest historical strata of the Indian diaspora — rooted in a civilisational exchange that predates modern migration, then reshaped by colonial-era indenture and the Kangani system, and revived by a new wave of IT and professional migration. The region is also central to India’s Act East policy and the ASEAN-centric Indo-Pacific vision. For UPSC GS-II, the Southeast Asia diaspora ties together history, Act East, ASEAN and economic diplomacy.
