In 1970, Nguyen Van Huy, in “Review in Movement BaYaRaKa” (16th April, 2004 in East Asia & Vietnam, BBC from http://www.bbc.co.uk/vietnamese/regionalnews/story/2004/04/040416_bajaraka.shtml), stated that the number of Cham who have fled from the Champa Kingdom (Central Vietnam) since the 14th to 16thcentury was 2 million in Indonesia, 200,000 in Malaysia, and 250,000 in Campuchia. This estimate was corroborated by The Malay Annals, published in the Journal of the Malayan Branch of the Royal Asiatic Society, vol. 25, Pts 2&3 No. 159, Singapore February, 1953, for October, 1952, translated by C. C. Brown, P.109-110, which stated that: “ ... Yak (Champa capital) fell and the Rija (king) of Champa was killed. And the children of the Rija of Champa together with the ministers scattered and fled in all directions. Two sons of the Rija, one of them named Indra Berma Shah and the other Shah Palembang, escaped by ship, Shah Palembang to Acheh and Shah Indra Berma to Malaka.”
