Prime Minister Yoshiro Mori instructed his economic ministers Tuesday to compile by early April a package of emergency economic measures to support Japan's fragile economy, government officials said.

Taro Aso, state minister in charge of economic and fiscal policy, will be primarily in charge of compiling the package, while other economic ministers, including Finance Minister Kiichi Miyazawa and Economy, Trade and Industry Minister Takeo Hiranuma, will help, the officials said.

The package will focus on revitalizing the stock market, accelerating bad-loan disposal by Japanese banks and improving liquidity in the real estate market, the officials said.
