The United Nations Office in Timor-Leste (UNOTIL) supported the capacity development of critical state institutions, including the Timor-Leste National Police (PNTL) in order to strengthen democratic governance and to help further build to peace in Timor-Leste.

A UN Police Force of Technical Advisers continues to provide the country's police, Policia Nacional de Timor-Leste (PNTL), with specialized training for rapid response and intervention units.

The Technical Advisers are also responsible for providing training in specialized areas such as counter-terrorism, forensics, and transferring management skills to the national police in all districts of Timor-Leste.

[citation needed] Following up on UNMISET, the Security Council passed Resolution 1599 authorising peace-building activities by establishing the United Nations Office in Timor Leste (UNOTIL).

United Nations Security Council Resolution 1677 extended UNOTIL's mandate one month past expiration[2] while forces from former INTERFET countries came to provide peacekeeping, the main force coming from Australia under Operation Astute.
