The world's richest nations have agreed to increase their aid to Africa and other impoverished areas despite economic slumps at home.

The agreement comes on the second day of talks between the ministers of the Group of Eight industrialized nations and emerging nations such as Brazil and China in Tokyo.

Japan's foreign minister says while the G-8 nations "are facing some big problems," they need to "seriously face" problems such as global poverty and take action.

He said the ministers also discussed the growing threats of climate change and rising food prices.

The talks opened a day after the Organization for Economic Cooperation and Development said aid from major donor countries slumped last year. It says the U.S. and other wealthy nations are falling behind targets set three years ago to help the world's neediest.
