The U.S. military's relocation of 8,000 marines from Okinawa in Japan to Guam is a key topic at a regional business conference which opens today.
The meeting in Guam explores investment, opportunities in the U.S. territories and Freely Associated States.
It is the fourth conference that's been organised by the U.S Department of Interior's Office of Insular Affairs.
The Deputy to the Secretary of Interior David Cohen says the US military move paves the way for lucrative contracts.
"Certainly there'll be the military construction opportunities here on Guam, but its also going to significantly increase the population and create demand for new housing, utilities, services and shopping - and hopefully create a demand for tourism in the region."
More than 800 business and trade delegates from the Asia Pacific region, including from New Zealand, are attending.
