Asian Development Bank President Haruhiko Kuroda voiced support Monday for Prime Minister Shinzo Abe's financial policies including the introduction of a 2 percent inflation target but kept mum about speculation he may become the next Bank of Japan governor.

In an interview with media organizations including Kyodo News, Kuroda said the BOJ's introduction of the target, proposed by Abe, was "epoch-making" and that the goal should be achieved "in about two years."

Kuroda, a former Japanese vice finance minister for international affairs, also said the central bank could carry out further monetary easing to help the country's flagging economy, saying, "There are still a lot of assets within Japan that should be purchased."
