"We in the World Bank must be sure that we deliver results," said the bank's president, Paul Wolfowitz, at the opening session. "And by results, let me be clear. I mean results that have a real impact in the day-to-day lives of the poor. We stand accountable to them."
An agreement Friday among finance officials of the world's seven wealthiest industrial countries should clear the way for final approval by IMF and World Bank leaders to the debt relief program, Treasury Secretary John Snow said.
The IMF's managing director, Rodrigo Rato, said the debt plan must get enough financial support from wealthy nations so it will not "cripple the fund's ability to provide support to low-income countries that need our help in the future."
The plan would erase more than $40 billion in debt owed by the world's 18 poorest nations, many of them in Africa, to the World Bank, the IMF and the African Development Bank.
President Bush and other world leaders settled on the outlines of the deal at an economic summit meeting in Scotland, in July.
But Belgium, the Netherlands and others said the rich countries were not making sufficient commitments to replace the money that the IMF and World Bank would forego.
Finance officials from the Group of Seven countries, joined by Russia's finance minister, pledged in a letter to Wolfowitz to "cover the full cost to offset dollar for dollar" the loan repayments the World Bank would lose. The G-7 nations are the U.S., Japan, Germany, France, Britain, Italy and Canada.
Snow said he believed the agreement would help overcome objections to the debt relief plan, leading to approval by the executive boards of the IMF and World Bank.
"It would be our hope they can do that quickly within a week," Snow said.
The G-7 also addressed soaring energy prices. The countries said they were committed to a broad plan intended to increase supplies, promote conservation and improve the release of timely data on oil production as a way of reducing wild price swings in global energy markets.
France's finance minister, Thierry Breton, said he and Britain's chancellor of the exchequer, Gordon Brown, planned to tour oil-producing countries in the next month on behalf of the G-7 to urge them to improve the timeliness and quality of oil market data.
"Today there is not enough visibility between demand and supply and oil markets are not as open as others," Breton said.
The finance meetings got under way as Hurricane Rita bore down on the Texas Gulf Coast soon after Katrina had caused widespread shutdowns of oil platforms and refineries along the Louisiana Gulf Coast.
Katrina sent gasoline prices in the United States above $3 per gallon and oil prices briefly above $70 per barrel.
Finance officials praised China's move on July 21 to stop linking its currency directly to the dollar. China allowed its currency, the yuan, to rise in value by 2.1 percent against the dollar and announced a further change to its currency system on Friday.
Snow said Saturday the action was "an important first step," but he said it was now "critical that we see further moves."
China's finance minister, Jin Renqing, said Beijing was pursuing "an independent and responsible" exchange rate policy. He did not indicate that a further revaluation was imminent.
American manufacturers complain that the small moves so far still leave the Chinese currency undervalued by as much as 40 percent, giving Chinese products a huge competitive advantage over U.S. goods.
