Prime Minister Shinzo Abe said Wednesday he wants the next Bank of Japan chief to fully understand his policies for battling chronic deflation and revitalizing the struggling economy.

Economic and fiscal policy minister Akira Amari is set to attend the central bank's Policy Board meeting next week, government sources said, adding to expectations that the BOJ will accede to the prime minister's directive to further monetary easing until achieving 2 percent inflation annually.

"We will choose someone who can appreciate my (goal to establish) basic policies to beat deflation," Abe told reporters, adding that a successor to BOJ Gov. Masaaki Shirakawa, who ends his five-year stint in April, must be a "person with firm determination and ability."
