The Office for the High Commissioner for Human Rights says tonight's review of Fiji' human rights record before the United Nations Human Rights Council in Geneva is important.
The review will be based on one report submitted by the interim regime, another by the UN, and a third by NGOs.
The office's regional representative, Matilda Bogner, says UN member states will discuss Fiji's human rights situation and will recommend areas for improvement.
Ms Bogner says Fiji's interim government will then be called on to respond in a couple of months.
"Fiji will have to state publicly which recommendations it commits itself to actually implement. So in that sense it's also a very important mechanism, because the state does need to publicly commit to making improvements to human rights and then can be held accountable to those committments in another four years time when it will be reviewed [again]."
Matilda Bogner says sanctions are no part of the process.
