"For us in the Blue Pacific, history may be calling," Rabuka told diplomats, Fijian community members, academics and policymakers at a function organised by the Australian think-tank, Lowy Institute on Tuesday.
"It might be our manifest destiny to carry banners for peace and speak out for harmony in our time, and forever."
Rabuka said he wants the proposal on a 'Pacific Peace Zone' to be discussed at the 52nd Pacific Islands Forum Leaders Meeting next month.
