Observers say Indonesia has been able to build peace between locals and the government in Aceh, Sumatra, amid locals' grievances over discrimination and human rights abuses. The turning point in Aceh was when the 2004 tsunami hit the Indonesian coast, academics say.
Both sides realised the fighting had to end so they could deal with the disaster.
After 29 years of conflict, the Free Aceh movement signed a peace deal with the government in 2005.
