I highly doubt that. But what it has done, coupled with a lot of factors, is created an undercurrent of seperatist resentment in East Malaysia (Sabah is not an island, it is a state in Borneo). In the early 90s a wave of politicians from West Malaysian parties won the elections in East Malaysia and have held firm since then, despite said dissent. They use tactics such as exploiting the strong tribalism in the island (think of Sabah and Sarawak as if the US put most of the Native American tribes in 2 big states, and isolated them so access to outside information is limited), bribing the community leaders so everyone in the tribe voted together, etc.
