TOKYO (AP) — Japanese and Russian foreign and defense ministers are meeting in Tokyo for talks expected to focus on security cooperation and a territorial dispute that has kept the nations from signing a peace treaty.

Russia has been expanding its trade ties in Asia and has sought closer relations with Japan, partly as a counter for China's rising military power.

The two sides will have only a preliminary meeting late Friday with the main discussions scheduled for Saturday.

Russian President Vladimir Putin has sought to revive progress toward an agreement on control of four islands that were captured by Soviet forces at the end of World War II. The two sides have also stepped up cooperation on developing energy resources and other trade in the Russian Far East.
