A spokesman for the SODELPA party says it is unfortunate that Fiji's Prime Minister, Frank Bainimarama, is leading the world's largest association of developing countries.
Fiji is currently hosting a two day meeting of United Nations G77 + China, a group which aims to promote economic co-operation among developing countries.
But Dr Tupeni Baba says it's unfortunate that the organisation is being chaired by a non-elected President.
He says it should be chaired by an elected Prime Minister, and not a military ruler.
Dr Baba says he will be sending his protest to the UN Secretary-General.
"Next time we should not allow any leader of the G77 to be a non-elected leader who contravenes the rights and freedoms that is endorsed by the UN."
