The administration plans to outline stimulus steps to buttress the slowing economy and counter the yen's rise, possibly by month's end, government sources said Thursday.

Chief Cabinet Secretary Yoshito Sengoku told reporters in the morning that the government is keen to draw up the stimulus measures "as soon as possible" after the policy research council of the ruling Democratic Party of Japan submits proposals.

Having initially planned to compile the steps at the start of September, the government has decided to speed up the process as the outlook for the economy is being darkened by the yen's rapid appreciation and falling stock prices, the sources said.
