Tokyo: Japan's foreign minister says no deal can be expected during President Barack Obama's visit later this week on a major plan to relocate US troops on the southern island of Okinawa.

Foreign Minister Katsuya Okada warned Sunday on a nationally televised news program against rushing to conclusions. He noted an agreement between the heads of state holds heavy significance - referring to the planned meeting between Obama and Japanese Prime Minister Yukio Hatoyama.

Obama is expected to arrive Friday, ahead of a weekend summit of Asian and Pacific leaders in Singapore.

Washington and Tokyo agreed in 2006 that Futenma base would be relocated to another part of Okinawa, and 8,000 Marines transferred from Okinawa to the US territory of Guam by 2014.

Japan underwent a change of rule in an August nationwide elections after decades of rule by the conservative Liberal Democrats.
