The United Nations' emergency relief coordinator Jan Egeland at first hinted that rich countries were being "stingy" with aid then later tempered his remark.
But it drew a sharp response from US Secretary of State Colin Powell, who said: "The United States is not stingy. We will do more. I wish that comment hadn't been made."
Japan has earmarked $40 million, the US has more than doubled its initial aid pledge to $35 million and Canada has promised $33 million to lead a string of countries - rich and poor - to roll out the world's largest international aid operation for decades to devastated coastal areas.
UN Assistant Emergency Relief Aid Coordinator Yvette Stevens said the international aid needed over the coming months was very likely to exceed the previous record UN appeal of $1.6 billion for Iraq last year.
Pledges poured in from traditional Western donors, as well as less common sources such as China, Brazil and Argentina, and even impoverished countries such as Cambodia, the UN said.
The International Federation of Red Cross and Red Crescent
South Korea has pledged
$2 million in relief funds
Societies (IFRC) appealed for another $44 million in immediate aid.
Oil-rich Saudi Arabia said it would contribute $10 million in emergency funding while Cambodia donated $40,000 to four of the stricken countries.
The US military said it had diverted an aircraft carrier, other
ships, and at least 20 aircraft to Asian countries, including much needed air cargo capacity.
But as the toll climbed past an estimated 60,000, emergency
funding appeared to be less of a problem than coordination and stricken countries such as India and Sri Lanka even started to turn down some offers of aid.
Indian authorities, despite having to deal with more than 9000 casualties, joined the aid effort for other stricken countries, promising $23 million and sending helicopters and aircraft to distribute food, medicines and blankets.
Sri Lanka asked Israel to scale down a proposed 150-strong
medical team, saying it had enough doctors and rescue personnel, but welcoming urgent Israeli supplies.
