The government may allocate funds for the relocation of a U.S. Marine base in the fiscal 2010 national budget before finalizing its stance on where the base should eventually be relocated, a high-ranking government official said Wednesday.

The possible budgeting for a new facility that would replace the U.S. Marine Corps Air Station Futenma in Okinawa reflects Tokyo's concerns that the United States may perceive Japan as having reneged on the bilateral accord stipulating the relocation.

"The budget and the conclusion on a relocation facility are separate issues," the official said on condition of anonymity.
