The Asian Development Bank is expected to take up issues of regional concern, including the U.S. economic slowdown and the yen's weakness, at its annual meeting next week, Japanese government sources said.

The ADB will also focus on reducing poverty and promoting information technology in the Asia-Pacific region as major topics at its three-day gathering, which starts Wednesday in Honolulu.

Japan, which will be represented by one of its two senior vice finance ministers, is poised to reiterate its policy of actively supporting developing nations, they said.
