efforts to unite Brunei, Sabah, and Sarawak under the North Borneo Federation but that failed after the Brunei Revolt occurred. The Borneo States retained a higher degree of local government and legislative autonomy than the States of Malaya. For example, both states have their own immigration controls, requiring Malaysian citizens from West Malaysia to carry passports or identity cards when visiting East Malaysia. The islands of Labuan were once part of North Borneo in 1946 before becoming a Federal Territory in Malaysia on 16 April 1984. It was used to establish a centre for offshore finance in 1990. Since 2010, there has been some speculation and discussion, at least on the ground level, about the possibility of secession from the Federation of Malaysia because of allegations of resource mishandling, illegal processing of immigrants, etc. Administration The Borneo States of Sabah and Sarawak joined the Federation of Malaysia as equal partners with Malaya and Singapore.
