Japan and several other developed nations are unlikely to fulfill pledges to boost development aid made at a Group of Eight summit in Britain in 2005, according to the Organization for Economic Cooperation and Development.

The Paris-based group said in a report released Wednesday that Japan's official development assistance in 2010 will probably come to around $9.5 billion, although the country promised at Gleneagles, Scotland, to increase ODA by $2 billion annually from $8.9 billion in 2004 for a total boost of ¥10 billion through 2009.

The OECD also projected that the ratio of Japan's ODA to its gross national product will stand at 0.20 percent in 2010, up only 0.01 point from 2004.

The organization said France, Germany and Italy will likewise fall short of pledges to boost their annual ratios of ODA to GNP.

In 2005, 15 members of the European Union promised to gradually boost their ratios to a minimum of 0.51 percent by 2010.

But France will likely reach only 0.46 percent, Germany 0.40 percent and Italy 0.20 percent, while Britain is expected to surpass that goal with 0.56 percent.
