The Solomon Islands Prime Minister Sir Allan Kemakeza leaves Honiara today to attend a United Nations Conference in Mauritius on the future of Small Islands Developing States.
The Solomon Islands Broadcasting Corporation reports more than 2,000 people will take part in the meeting including, donor partners and some 25 heads of state and government.
The leaders are to review the programme of action for sustainable development.
Sir Allan says the meeting is crucial because of the destruction caused by recent tsunami in the Indian Ocean.
He says like many of the small island countries, Solomon Islands is vulnerable to natural disasters such as cyclones, earthquakes and sea surges.
Sir Allan says this also affects economies because of the increased globalisation, making small economies vulnerable to international market shocks because of their smallness and distance from export markets.
The summit begins on Monday.
