During and after the devastation of WW2, many Tamils and other Indians from Burma fled to India- to Manipur, and Tamil Nadu. They established Burmese refugee colonies that still exist today and maintain an identity as Burmese returnees. In Sri Lanka the Sinhalese nationalist SLFP party disfranchised all Indian origin Indian Tamils of Sri Lanka and returned 600,000 back to India under the Srimavo-Shastri Pact signed between India and Sri Lanka. Many were repatriated to the Nilgiris region's tea estates. They too maintain a distinct identity as Ceylon returnees in Tamil Nadu. Black July has created another stream of Sri Lankan and Indian Tamils of Sri Lanka refugees in India who have languished for the last 20 years in refugee camps throughout Tamil Nadu while many others have integrated with the mainstream community or left India for other countries in the west.
