Generally, the bilateral relations between India and Sri Lanka have been friendly but the long Sri Lankan civil war involving ethnic Tamils and the failed Indian interference during the war did hamper the good relations. Sri Lanka’s only neighbour is India, both countries separated only by the Palk Strait. Both countries hold strategic positions in South Asia and are keen to make a common security umbrella in the Indian Ocean. The countries also share strong cultural and historic ties with about 70% of Sri Lankans professing Theravada Buddhism. Buddhism spread to Sri Lanka from India, the place of the religion’s birth. Off late, however, China has inched closer to Sri Lanka by signing naval agreements. India, to augment relations, has entered into a nuclear energy deal with Sri Lanka.
