I really suggest it, for real. The case is in Papua they feel they are not part of us because they are different from other parts of Indonesia racially and ethnic, this will be the case even till two or three hundreds years from now if the Natives still being a majority in Papua. To encourage more imigran there and promote interracial marriages will solves this cultural identity problem in the long run, to made the pure Native as minority should be long run objectives. You should now, there is not only Javanese come to Papua, but Bugis, Batak and Moluccan came there and have sizeable presence there. Papuan as long as they had this kind of identity crisis there they (the rebels movements) still can play this racial cards in the long run.
