The controversy arose because the Singo Barong mask on the official website of Ministry of Tourism, Arts and Culture of Malaysia contained the words "Malaysia" on it and recognized as a legacy of Muslim Javanese communities in Malaysia especially in the district of Muar, Johor. The origins and cultural ownership of the Reog dance have been the subject of a dispute and controversy between the neighboring countries of Indonesia and Malaysia, whose ethnic, cultural and religious histories overlap and share many similarities. Mostly because there is numerous descendants of Javanese immigrants in Malaysia, some who have been serving with Sultan of Malacca, before moving together with the Sultan, especially in Johor state to form Johor-Riau Sultanate. And some of the immigrants brought many Javanese-origin artforms such as Barongan, Wayang Kulit Jawa, and Kuda Lumping. Thousands of Reog artist had a demonstration at the Malaysian Embassy in Jakarta. To avoid further controversy with Indonesia, all promotional revival on Barongan have been discontinued by the government of Malaysia, which contributing to further decline of Barongan in Malaysia. However, Malaysian government continue to promote other ethnic culture like Portugis descendant, San Pedro Day. Bibliography
