But as the clock ticks and conditions in refugee shelters deteriorate the political pressure on Burma is likely to grow.
Britain's U.N. ambassador, John Sawers, has indicated that a high-level conference would be more than a donors' meeting, calling it a "major international meeting" in line with Prime Minister Gordon Brown's calls for a U.N. summit on coordinating aid efforts in Burma.
U.N. Secretary-General Ban Ki-moon has also proposed appointing a joint coordinator from the U.N and the Association of Southeast Asian Nations (ASEAN) to oversee aid delivery and has said he would soon send the U.N's humanitarian chief John Holmes to Burma.
The Secretary-General of ASEAN urged patience when dealing with the generals.
"We are trying to work around a very, very strict resistance and mentality and mindset that have been there for a long, long time," Surin Pitsuwan, a former Thai foreign minister, told an audience at the Council on Foreign Relations in Washington.
JUST HELP
The former Burma was once the world's biggest rice-exporting country, but more than 40 years of military rule have left it impoverished. The military rulers have repeatedly crushed pro-democracy movements and tightly restrict visits by foreigners.
A senior U.S. military official in Washington said there were signs aid was stacking up at Yangon airport and said Washington wanted to fly choppers to the areas hit worst.
Officials said that despite reports some supplies were being stolen or diverted by the army, the humanitarian needs were so great that they would keep making deliveries - while continuing to urge that U.S. aid workers be granted visas.
As diplomatic efforts roll on, U.S. emergency aid flights will continue and non-governmental organisations with local staff continue to do what they can.
"I think at this moment we have to drop politics and just help," said Frank Smithius, head of Medecins Sans Frontieres.
"The army is definitely distributing food in certain areas, they're not doing nothing. But it's not enough. In some areas there's enough food but not enough water and shelter. In other areas we see that they have nothing."
