Of the 6.7 billion dollars (5.1 billion euros) pledged, about a tenth has yet to be delivered, and only 3.4 billion dollars has been spent thus far, the BBC said.

Among the countries that came up with a fraction of what they promised, China offered 301 million dollars to help Sri Lanka recover from the disaster, but has thus far delivered just one million dollars, the broadcaster said.

Spain pledged 60 million dollars to Sri Lanka, but came up with less than a million, while France said it would give 79 million dollars, but delivered just over a million dollars.

Kuwait had pledged slightly less than 10 million dollars to the Maldives, but has yet to actually hand over any money.

The United States has given about 38 percent of the money it promised, according to the UN figures. The European Commission owes about 70 million dollars, and Britain 12 million.

The broadcaster said on its website that about nine percent of the total money pledged was not yet delivered.

The BBC said that of the 2.2 billion dollars donated to the Red Cross worldwide in the aftermath of the disaster, about 1.3 billion dollars had not yet been spent, and of the 50,000 homes promised by the Red Cross, just 8,000 had been finished.

Speaking to the BBC, the international director for the British Red Cross defended its performance: "It sounds bad, but I think it needs to be put into context."

"It is incredibly difficult ... we said from the beginning, this is happening in very difficult circumstances. We raised the money knowing it was difficult. It will take time to spend this money in a responsible manner," Matthias Schmale said.

He said that the British Red Cross had thus far finished 16 of the 2,000 homes it had promised, with 265 ready to be handed over, and a further 400 would have their foundation laid by the end of this month.

"I know this sounds like slow progress ... When the tsunami swept away houses, it also swept away identity papers, legal plot papers, etc. We have taken almost a year to help people back ... to make sure they have legal ownership of their plots," he said.

The UN's special rapporteur on adequate housing Miloon Kothari was unimpressed by the reasons for delays in building housing, telling the BBC: "It should really not take this long to build permanent housing.

"I do not accept the explanation that it is going to take four to five years, in some cases, seven. I'm an architect, I know how long it takes to build a house."

Early on December 26, 2004, a magnitude 9.3 earthquake off the Indonesian island of Sumatra triggered an ocean-wide tsunami that killed 220,000 people.
