Japan and its central bank will keep up joint efforts to ensure stability in the nation's financial sector and fight deflation, Bank of Japan Gov. Toshihiko Fukui said Sunday.

Addressing a meeting in Dubai of the International Monetary and Financial Committee, Fukui said Japan will continue to pursue comprehensive structural reforms in such areas as regulation, the financial sector, taxation and government spending in a bid to ensure sustainable economic growth.

The BOJ is "firmly committed to" maintaining its ultra-easy monetary policy until the consumer price index registers zero percent or above in a stable manner, he said.

The comment apparently was intended to keep financial markets from pushing up long-term interest rates on expectations that the BOJ's quantitative easing policy is about to end.
