Commission President Jose Manuel
Barroso said in Jakarta he would also seek the European
Parliament's approval for an additional 350m euros ($464m)
for long-term reconstruction.
Meanwhile the US said it was disbanding
what it called the core group of nations formed to tackle
the crisis.
The BBC's Laura Trevelyan at the
UN says officials who had feared that the core group would
duplicate the UN's efforts will be quietly relieved by
this move.
World and local leaders, aid groups
and international organisations are attending the Jakarta
conference.

The conference also agreed the establishment
of an early warning system in the Indian Ocean.

Generosity praised
Mr Annan said the UN had drawn up a "focused set
of programmes" tending to the immediate needs of
the survivors of the tsunami.
But he warned that the number of fatalities
could double if aid did not reach survivors soon.
"There are daunting logistical constraints. But
they are not insurmountable. It is a race against time,"
he told world leaders.
The programmes - costing a total of $977m - would include
$215m towards food, $222m toward shelter and $122m towards
healthcare.
The biggest single recipient would be Indonesia, the
worst-hit country, which would receive $371m of the immediate
aid, with the remainder spread across the rest of the
region.
Although the UN has praised global generosity in responding
to the disaster, aid agencies warn that in past disasters,
pledges have not always been honoured.
Just more than a year ago donors promised Iran more than
$1bn to assist with the Bam earthquake disaster. Iran
complains that only $17.5m ever arrived.
Early warning
Other pledges may come as loans, in services and equipment
or be earmarked for long-term reconstruction purposes.
