The US military's Joint Guam Programme Office says nothing has changed in their planning for the transferral of 8-thousand marines to Guam.
This is despite further uncertainty cast over the transferral after Japan's Prime Minister delayed a decision over a plan, relocating troops currently on the Japanese island of Okinawa, for at least another six months.
Japan's government has been reviewing a 2006 agreement with the US which provides for the transferral of the marines from Okinawa to Guam by 2014.
The office's public affairs officer, Captain Neil Ruggiero, says Japan's delay has no bearing on their extensive preparations on Guam.
"Still on track. No plans have changed at all. Our mission is to make sure that the planning is done correctly for the marines to move from Okinawa to Guam and that is what we're going to continue to do, to oversee the building of the construction of the base, the planning and construction."
