The Indonesian government and rebels from Aceh province plan to sign a formal peace deal on August 15.
The agreement will bring an end to a nearly three-decade war between the Free Aceh Movement and the government in Jakarta.
A joint statement following peace talks in Helsinki, Finland, Sunday says the agreement will bring "a peaceful, comprehensive, and sustainable" solution to the conflict in Aceh, which has cost some 12,000 lives since 1976.
Though details of the agreement have not been released, the two sides say it covers political participation, human rights, an amnesty, and security arrangements in the province.
Peace efforts gained momentum this year following the December tsunami that devastated Indonesia's Sumatra island, where Aceh is located.
