Passages:
Arie Supriyatna (born on December 25, 1984) is an Indonesian footballer who currently plays for PSMS Medan in the Indonesia Super League. The Indonesia–Timor Leste Commission on Truth and Friendship was a truth commission established jointly by the governments of Indonesia and East Timor in August 2005. The commission was officially created to investigate acts of violence that occurred around the independence referendum held in East Timor in 1999 and sought to find the "conclusive truth" behind the events. After holding private hearings and document reviews, the commission handed in the final report on July 15, 2008 to the presidents of both nations, and was fully endorsed by Indonesian President Susilo Bambang Yudhoyono, providing the first acknowledgement by the government of Indonesia of the human rights violations committed by state institutions in Timor. The commission is notable for being the first modern truth commission to be bilateral.
