The tournament provides preparation for Fiji, Tonga, Japan and hosts Samoa ahead of the 2011 Rugby World Cup.
The IRB said the award of the tournament to the Samoa Rugby Union represents a “further boost” to the continued development and promotion of rugby both in the country and across the whole of the Pacific Islands.
“Samoa has a rich and proud Rugby heritage and I am sure that the Samoa Rugby Union will embrace the opportunity to showcase their country and the Union with the first major international fifteen-a-side tournament to be hosted in the country,” said IRB Chairman Bernard Lapasset.
“The Game continues to achieve growth around the world through the IRB's £48 million Strategic Investment Programme, and this tournament is a key element, providing the Participating Unions with an expanded competition calendar and a dedicated player development pathway aimed at increasing competitiveness at Test level, and ultimately at Rugby World Cup."
The two-week tournament kicks off on June 12.
