Ten Pacific Island countries are said to have confirmed their attendance at the "Engaging Fiji" meeting this week.
Fiji Broadcasting reports the countries are Papua New Guinea, Solomons, Kiribati, and Tuvalu as well as seven other Island states.
Vanuatu has confirmed they will be attending and will be represented by either the Deputy Prime Minister or the Foreign Affairs Minister.
The meeting was set up to replace a Melanesian Spearhead Group summit that was cancelled at the last minute after the current MSG chairman,Vanuatu's Prime Minister, Edward Natapei, said there were ramifications to Fiji's non elected leader chairing the body.
Fiji's Foreign Affairs Minister, Ratu Inoke Kubuabola, says the confirmation of attendance at the alternative meeting demonstrates the support that Fiji has throughout the Pacific.
At the meeting, the interim Prime Minister, Frank Bainimarama, will brief Island Leaders on the progress of Fiji's Roadmap for Democracy and Strategic Framework for Change.
