Japan aims to seek global understanding of its aggressive monetary easing at this week's meeting of Group of 20 finance chiefs to ease possible concerns about the yen's recent steep fall and negative effects that could spill over to other economies.

Bank of Japan Gov. Haruhiko Kuroda and Finance Minister Taro Aso are likely to explain that the bank's drastic easing steps are intended to shore up the domestic economy and to reaffirm that Japan will refrain from competitive devaluation as agreed to at the previous G-20 meeting in February.

Kuroda, who will make his international debut as BOJ chief at the meeting starting Thursday in Washington, is expected to say the BOJ's new easing steps are aimed at achieving its 2 percent inflation target to beat prolonged deflation and will eventually have favorable effects on the global economy.
