Japan has pledged $17 billion in development aid to other Asian countries for infrastructure projects that will help boost growth.
Speaking Saturday to the World Economic Forum in Davos, Switzerland, Japanese Prime Minister Taro Aso also repeated a pledge to lend $100 billion to the International Monetary Fund.
Mr. Aso also announced a new greenhouse gas emissions plan for Japan and pledged to announce emissions targets by June.
The Japanese leader planned to spend only half a day in the Swiss mountain resort and return home by late Sunday to deal with a stormy session of parliament, where the opposition hopes for a victory in elections that are required to be held this year.
