The Japanese economy is strong enough to recover from the impact of devastating earthquake and massive tsunami, the International Monetary Fund (IMF) said Thursday.

"We believe that the Japanese economy is a strong and wealthy society and the government has the full financial resources to address the humanitarian needs, the infrastructure needs and reconstruction and addressing the nuclear situation," Caroline Atkinson, an IMF spokeswoman, said at a news conference.

The IMF stressed that Japanese authorities were taking "the appropriate policy" to tackle the impact of the disaster and "revive the Japanese economy."

Japan has injected huge amount of money into its shaky financial system after the 9.0 magnitude earthquake struck last Friday.

In total, 34 trillion yen (about 425 billion U.S. dollars) of funds have been added to money markets since Monday.
