It is true that Indian diasporas in Southeast Asia are considered to be a significant source of strengths for India. They constitute considerable percentages in some members of the region while they demonstrate their own positions in terms of economy, politics and culture in both Southeast Asia and in India. This is going to be reflected in the paper called “Indian diasporas in Malaysia, Myanmar and Singapore: Origin and roles”. To achieve this researching purpose, this article is going to: (i). discover the origin of Indian diasporas in the region; (ii). explain the economic, political and cultural roles of Indian communities in some countries in Southeast Asia including Myanmar, Singapore and Malaysia; (iii). highlight their valuable contributions to India in terms of remittances and culture. Thanks to those mentioned researching tasks, this paper is expected to help us evaluate Indian diasporas in Southeast Asia as an integral part of Indian diasporas in the world.
