The religious and cultural links between Sri Lanka and Cambodia dates back to the 5th Century as the epigraphical evidence suggests that Mahavihara and Abhayagiri of Sri Lanka had made an early impact on the development of Theravadha Buddhism in South East Asia, when a substantial part of this region was dominated by the Mon Khmer culture, which later became part of the Khmer empire.The historical relations are based on Buddhism as both countries practice Theravada Buddhism.
